Neil deGrasse Tyson just rained all over Baker Mayfield's alien parade ... saying the Cleveland Browns quarterback most likely saw a meteor -- NOT a UFO.

Booooooooo.

Remember, Mayfield tweeted with "almost 100%" certainty he and his wife saw a UFO Wednesday night ... saying they saw a "very bright ball of light going straight down out of the sky."

But, Tyson -- certified science nerd -- says Baker needs to come back down the earth ... and suggests the QB brushes up on his meteor knowledge.

"Okay, so what he should do is go look at what meteors look like and most of them look like simple shooting stars," Tyson said Friday on FS1's 'The Herd' with Colin Cowherd.

"But, the occasional one, the occasional BIGGER one is called a bolide. We have special words for them and they flash through the sky. It takes just half a second! It flashes through the sky and at the end, sometimes they explode."

In other words, don't expect an alien invasion just yet, Bake.

Tyson says there are a bunch of amateur astronomers who spend countless hours looking in the sky ... and there would be a lot more hubbub if it really were anything out of the ordinary.

"I think if there were aliens visiting, the astronomer community would catch it immediately."

Elon Musk founding his City of Starbase, Texas is getting support from at least one local official ... who says the move could lead to a serious job and tourism boom.

Joey Lopez, one of four elected commissioners for Cameron County, tells TMZ ... Elon's SpaceX has already made an impact -- currently known as the unincorporated area of Boca Chica Village -- by attracting tourists who come watch rocket launches.

Hopefully, the rockets will do better than the one Wednesday ... an unmanned test flight of a SpaceX rocket Elon hoped would go to Mars exploded after trying to stick a clean landing at the South Texas landing facility.

Lopez says SpaceX has also created jobs in the area. He says in June of 2020 there were 600 county residents who worked for SpaceX. That number's swelled to as high as 1,800 ... according to Lopez.

And, if Elon starts his own city ... Lopez sees that number skyrocketing. #PunIntended.

What's more ... Lopez says Elon's already ingrained himself in the community ... like recently helping save sea turtles during Texas' recent deadly winter storm. He also provided generators that helped maintain water pressure in two Cameron County towns.

As we reported ... a county judge has already said Elon must comply with all state laws if he wants to own a piece of Texas. Lopez says Elon has a lot of work to do if he wants Boca Chica Village Starbase to become a self-sufficient city.

Elon Musk has some expensive bugs to fix -- another unmanned test flight of a SpaceX rocket he hoped would go to Mars went up in flames.

SpaceX nearly completed the successful test flight Wednesday at its facility in South Texas. The plan is for this prototype spacecraft, called SN10, to eventually venture all the way to Mars -- but several minutes after a clean launch and return trip to Earth ... it exploded.

SN10's launch was delayed due to a sputtering engine earlier in the day, but fired up for lift-off around 3 PM PT. It completed its route -- which wasn't meant to go too far up -- and touched down again, seemingly without a hitch.

The official SpaceX broadcast cut out before folks at home could see it blow up, but other streams that were monitoring the action live sure caught the blast.

You can hear someone who was watching it talk about a methane leak, but SpaceX has not said what caused the blast.

We've seen this before with SpaceX's Starship test flights -- this exact thing happened last year at the same facility ... with the same result.

They gave it another go just last month, and the results were identical ... fireballs. Again, these were all unmanned launches.

The first super clear images from NASA's Perseverance Mars Rover are in, and ... wow!

You can see it's going to be a rocky road -- literally -- for the Rover when it gets going and cruises around the red planet. NASA had a little fun with these images when the spacecraft's Twitter account (yes, it's got its own) tweeted the images ... saying, "I love rocks. Look at these right next to my wheel. Are they volcanic or sedimentary? What story do they tell? Can’t wait to find out." Same, TBH.

NASA also showed a clear image of the open horizon. The pics come one Earth day after the Mars Rover stuck the landing Thursday ... the tail end of an incredible 293 million mile journey.

As we reported ... Perseverance blasted off from Florida's Cape Canaveral back in July and touched down at exactly 12:56 PM PT on Thursday. Pretty cool moment when the folks over at NASA's mission control celebrated the landing and fist-bumped from California's Jet Propulsion Laboratory.

It's going to be fun seeing more images rolling in soon. As we told you ... the SUV-sized spacecraft also brought along a small helicopter along for the first time ever.

NASA's Mars rover landed safely on the Red Planet ... and its 293-million-mile journey is just beginning.

The Perseverance rover touched down at 12:56 PM PT Thursday, and quickly sent back the mission's first image from Mars' surface. As you can see, there's lots of dirt, dust and rocks.

NASA's mission control cheered and fist-bumped from California's Jet Propulsion Laboratory when the rover survived the landing ... a fun payoff after tons of hard work. Normally there would be bear hugs, but the celebration was spaced out and masked up.

Perseverance blasted off from Florida's Cape Canaveral way back in July, and now it's set to start exploring Mars' Jezero Crater in search of signs of ancient life. The crater is the site of an ancient lakebed, which scientists say is loaded with the remains of long-dead microbes.

The SUV-sized spacecraft even brought a small helicopter along for the first time ever, so more space history is on the way. When the chopper takes flight later on in the mission, it will be the first such flight on another planet.

Everything's rosy for Elon Musk's Starship spacecraft, except for those damn crash landings -- but somehow his engineers are keeping a remarkably positive outlook.

SpaceX's latest unmanned test flight of Starship -- designed to ferry cargo and people to the Moon and Mars -- ended Tuesday the same way it did in December ... with a fireball.

We'll say this ... the reusable capsule looked beautiful on the way up ... but it's that return flight that gets tricky. It's supposed to land vertically, but instead, it came down at an angle and burst into flames.

Bummer right? Not at mission control, where the mushroom cloud didn't stop an engineer from getting out his pom-poms to cheer up the team.

As the smoke was still rising, he bellowed, "Another great test flight" ... described everything that went right and then deadpanned, "We've just to work on that landing a little bit."

There's good reason for Captain Obvious to be so optimistic. Elon predicted Starship's initial test flights would likely crash land, and the primary objective is gathering data. See? Mission accomplished!!!

SpaceX is proving rocket launches never get old, because its latest mission had the precision of ... well, the Rockettes.

The spacecraft shook the ground Sunday at Cape Canaveral in Florida. The mission hurled a bunch of small satellites from both the government and private sectors. There was also SpaceX's Starlink broadband satellite.

The launch was originally set for last month, but was postponed for various reasons. It was scheduled to blast off Saturday, but Mother Nature had other ideas.

What's really amazing ... this is the 5th time the booster was used to rocket SpaceX payload into orbit. It made a perfect, bullseye landing. Really incredible.

A renowned Harvard physicist has a bold theory -- a celestial object that hurled through our solar system in 2017 was actually not of our galaxy ... but from another, perhaps light-years away.

Avi Loeb -- whose new book, "Extraterrestrial: The First Sign of Intelligent Life Beyond Earth," delves more into his hypothesis -- came on "TMZ Live" Tuesday to explain why a massive, sleek unidentified piece of debris that crossed our path in 2017 might've been other-worldly.

Check it out ... Avi says when it was studied by physicists and other scientists at the time, it had none of the makings of a typical asteroid or meteor that we would see from a distant star in the Milky Way. On the contrary, he explains that it was actually propelled by an unknown source, and appears (to him, anyway) to have pierced through from a faraway place.

The Chairman of the Harvard Astronomy Dept. goes on to break down how he and his contemporaries think the object was catching flight ... it's a technology that's beyond our grasp at this point, but one that could describe how the 100-yard entity moved how it did. Think 'Star Wars' hyperspace ... and now, add light to the mix. That's pretty much what Avi believes happened here.

As for what exactly it could be ... Avi's said it might be nothing more than space junk. But, whose space junk is the key question. In his eyes, it ain't ours ... which is extraordinary.

If you saw an extra bright star in the sky Monday evening, you're not alone -- our Solar System's 2 biggest planets crossed paths ... closer than they've been since the year 1226!!!

Monday's winter solstice -- the longest night of the year -- happened to coincide with a rare celestial occurrence star-gazers call the Great Conjunction, when Jupiter and Saturn align in their respective orbits around the sun ... only this time, they got extra cozy in space.

While Jupiter will pass Saturn every 20 years, the last the gas planets appeared as together as they do this right now was some 800 years ago. That time, they nestled up too close to the sun, so hardly anybody could see. Now, they're crystal clear in the night sky.

It's a rare, cool thing ... one that's colloquially been called the "Christmas Star" -- y'know, from the Bible and all. The planets might look conjoined to the naked eye, but even then -- they're about one-tenth of a degree apart from our vantage point.

Up there, though, they're really hundreds of millions of miles apart. Still, there's no way you could've missed their closest point Monday if you looked to the southwest shortly after sunset ... assuming weather conditions allowed for a peek. Tons of folks snagged photos too.

Jupiter and Saturn will remain in close proximity for the remainder of the month, but after that, they'll drift back apart to their usual distance.

It sounds crazy and undoable, but there are plans to colonize the Moon, and frankly, it looks kinda awesome.

Here's the thing. NASA is promising 2 astronauts -- a man and a woman -- will hurl to the Moon by 2024. Part of the mission is to study colonization of the Moon, using lunar materials to build structures where astronauts could live and study the surface and atmosphere.

The cylinders in the photo would protect astronauts from radiation and below zero temps. They would be built with regolith, which is a fancy term for lunar dirt. Scientists believe the regolith could be used to create bricks, which harden under the heat of the Sun.

As for breathable air ... the crater where the colony would sit contains ice, which contains oxygen and hydrogen.

Scientists are calling the colony "Moon Village." NASA is thinking of using the Moon as home base to launch astronauts to Mars ... as early as the next decade.

None of this could be accomplished without power ... but solar panels reflecting the Sun's heat would do the trick.

Elon Musk, we have a problem.

SpaceX's much-hyped high-altitude test flight of Starship -- a spacecraft designed to take people and cargo to the moon and Mars -- ended in a fireball as it crash-landed Wednesday in South Texas.

Video shows the large reusable capsule, which is supposed to land vertically, came down way too hard and instantly exploded. However, even though the footage is crazy ... it was not unexpected.

Musk predicted Starship would likely crash land, but said data gathered in the test flight would be critical in moving the mission forward. SpaceX stated ... "With a test such as this, success is not measured by completion of specific objectives but rather how much we can learn."

The guy who used to run Israel's space security program is sounding the alarm -- claiming aliens are real, and they're secretly working with our governments and biding their time.

Haim Eshed reportedly told the Israeli publication Yediot Aharonot he can confirm the existence of aliens, because he claims they've been among us for a damn long time. He even says they have their own org ... the "Galactic Federation."

Not only that, but Eshed -- who worked for the Israeli government from '81 to 2010 -- also alleges President Trump was about to blow the lid off the whole thing recently, but that he was convinced to shut his trap, 'cause most humans weren't ready for the truth ... yet.

The 87-year-old reportedly said, "There’s an agreement between the U.S. government and the aliens. They signed a contract with us to do experiments here. They, too, are researching and trying to understand the whole fabric of the universe, and they want us as helpers."

So ... they come in peace???

One more outlandish claim -- Eshed said there's an underground space base on Mars RIGHT NOW, where man and alien are working side-by-side for the betterment of the "Federation."

Ooookay ... so why's he going public? Much like comedy, Eshed says it's all about timing -- noting that if he had brought this up 5 years ago, he would've been written off as nuts.

BTW, plenty of people are still going with that take ... insinuating the dude's not all there anymore.

Conspiracy theorists, on the other hand, are pointing to Trump's fascination with ramping up Space Force, as evidence Eshed's on to something. And, don't get us started with UFO sightings either.

Remember, Obama all but confirmed the existence of aliens himself too -- but wasn't as loose-lipped as old Haim is here.

NASA sent a massive goody bag of supplies and treats up into space this week to help their astronauts out for the holidays -- and we found out what they're noshing on!!!

A rep for NASA tells TMZ ... part of the resupply load, aboard a SpaceX capsule, that docked at the International Space Station Monday were thousands of pounds of cargo for scientific research -- and also some fresh grub.

We're told among some of the fresh food items -- which is a rare treat in space, since most everything is either freeze-dried or thermostabilized -- was a bunch of fruit. Sounds basic, but in space ... even a first bite at the apple is something to savor for these expeditions.

Some of that produce included Gala apples, navel and blood oranges, mandarin oranges, and ... lemons!!! Hey, when life gives 'em to you, gotta make the most of it right???

We're told there were also some holiday-themed hot foods sent up as well -- which are all probably arriving in some type of airtight packaging, a la Tang.

Among that lot, NASA says it shipped stuff like cherry blueberry cobbler, cornbread dressing, cranapple dessert, jellied cranberry sauce, macaroni & cheese, potatoes au gratin, roasted turkey, shortbread cookies, southwestern corn, sparkle gel, spicy green beans, french vanilla cappuccino and wheat flatbread. Mmmm -- space munchies 😁.

BTW, these are the same astronauts that were shot up into the sky a few short weeks ago in another SpaceX Dragon capsule. So, they're probably due to a fresh shot of fuel.

There's a mysterious object hurtling toward Earth right now that will whiz past us early Tuesday morning, and in perfect 2020 fashion ... nobody's sure what the heck it is.

The unknown space mass has been dubbed "2020 SO," and is set to fly by our planet at an extremely close, but safe, distance of 31,605 miles at 3:50 AM ET December 1.

The object was discovered by the Pan-STARRS survey in Hawaii back in September, and initially, it was believed to be an asteroid measuring an estimated 15-33 feet across.

However, scientists at NASA's Center for Near-Earth Object Studies (CNEOS) soon began to postulate it wasn't an asteroid or even a "natural body" at all.

Instead, CNEOS director Paul Chodas is on record saying he believes the object is the Centaur rocket booster from NASA's failed Surveyor 2 lunar mission ... which launched way back on September 20, 1966.

Chodas used a bunch of computer science and math to track 2020 SO's orbit backward to come to the conclusion ... that it likely launched from Earth.

Of course, scientists will be able to more closely observe the object as it approaches to determine exactly what it is ... and here's to hoping it's more exciting than a hunk of space junk.

Not likely, though.

Barack Obama got the lowdown as Prez on UFOs -- or the lack thereof -- and although he won't say if space aliens are a thing, his facial reactions are more than interesting.

Obama appeared on 'The Late Show' Monday night and Stephen Colbert asked the burning question ... whether 44 was briefed on UFOs. He was quick to answer -- yes. After all, the Roswell mystery has survived for decades, so presidents are all looped in.

So SC asked the obvious followup ... what do ya know?  For that, you just gotta watch his reaction. Colbert thinks it's a giveaway ... that there's something in the air.

Then again, Obama could be clowning everyone ... after all, he's played his share of poker, but Colbert thinks the Prez betrayed his poker face and gave an answer loud and clear.

SpaceX and NASA are about to once again send astronauts into space -- laying even more groundwork for what might become a regular thing ... and we'll be streaming the event live, with lift-off slated for 7:27 PM ET.

Elon Musk's shuttle program is embarking on yet another launch Sunday from the Kennedy Space Center in Florida -- where the SpaceX team is firing its famed Dragon capsule into orbit ... only this time, it's carrying a few more helmeted cadets on the mission.

Three American astronauts are signed up for this job -- NASA's Mike Hopkins, Shannon Walker and Victor Glover -- and so is a Japanese astronaut named Soichi Noguchi. Check out their suits, BTW ... super sleek compared to what they used to rock back in the day.

That's technology, baby!!! Also ... fashion.

The 4-person crew is heading to the International Space Station, where they'll conduct scientific research for NASA. This is the second time this year that SpaceX has sent up humans in partnership with NASA -- in May, they sent up astronauts Doug Hurly and Bob Behnken to the ISS for a couple months ... now, they're upping the manpower. It's the first SpaceX commercial crew trip to the ISS.

This latest mission is a huge milestone -- it marks a huge pivot away from our reliance on Russian space travel -- something the U.S. has been heavily reliant on in recent years.

The fact SpaceX is helping with these types of trips more regularly proves it's a leading company for a lot more travel in the near future -- which could open the door for space tourism. The possibilities are endless, really.

The launch is scheduled for 7:27 PM ET. Houston, we have lift-off ... hopefully.
