Watch pieces of comet debris burn up in the night sky.

Diamonds found in a meteorite that exploded over the Nubian desert in Sudan a decade ago were formed deep inside a “lost planet” that once circled the sun in the early solar system, scientists say. Microscopic analyses of the meteorite’s tiny diamonds revealed they contain compounds that are produced under intense pressure, suggesting the diamonds formed far beneath the surface of a planet.

Famous astrophysicist Neil deGrasse Tyson and Goldman Sachs share a common belief: The next trillion-dollar industry will be in the mining sector—in outer space. As Neil deGrasse Tyson puts it: "The first trillionaire there will ever be is the person who exploits the natural resources on asteroids. There's this vast universe of limitless energy and limitless resources. I look at wars fought over access to resources. That could be a thing of the past, once space becomes our backyard."

The hypothetical cosmic portals linking two points of space-time that we call wormholes are the stuff of science fiction and space theory right now – but if they really do exist, one scientist has come up with a way we might spot them: by the shado

While the world was busy doing its thing on Saturday, a giant asteroid the size of a football field whizzed by our planet.

BERLIN (AP) — Fragments of a meteorite that fell to Earth about a decade ago provide compelling evidence of a lost planet that once roamed our solar system.

Here we go again: Fresh reports claim that the end of the world is nigh. Forgetting that we were all a little burned out by the 2012 end-of-Maya-calendar debacle, outlets such as the Daily Express are claiming that the Rapture — the end-time event when Christians are said to ascend to heaven at the second coming of Christ — is coming April 23 and we should get ready for it. In case you were inclined to jump on the Armageddon bandwagon, know this: The reports are bogus, and the celestial bodies aren't even in the predicted position for this supposed doomsday to occur!

There’s a great world next door. Let’s go. The search for alien worlds and perhaps alien life will take another step outward this week when TESS, the Transiting Exoplanet Survey Satellite, is launched into orbit around the Earth. TESS will spend at least two years scrutinizing the entire sky for exoplanets — planets around other stars — within about 300 light years from here. The worlds next door.

Well-heeled space tourists will have a new orbital destination four years from now, if one company's plans come to fruition.

The Exploration Upper Stage seems nowhere near readiness.

A stray Moscow pup traveled into orbit in 1957 with one meal and only a seven-day oxygen supply

A viral story that's making the rounds online claims Buzz Aldrin, the famous astronaut who traveled with Neil Armstrong to the moon aboard Apollo 11, somehow proved via a lie-detector test to have seen a UFO in outer space. Let's be very clear here: This is flat-out wrong. Here's why. First, the news reports misrepresent what Aldrin actually said. In a Reddit comment three years ago, Aldrin said that, while he did see something shiny out the window in space, he believes it was the sun reflecting off one of four discarded panels from his own spacecraft.

A telescope in outback Western Australia has been used to listen to a mysterious cigar-shaped object that entered our Solar System late last year.

China hopes to create a 'mini biosphere' on the dark side of the Moon, with flowers and silkworms sustaining each other as they grow on the lifeless lunar surface. The unprecedented plan to create life in outer space is the most intriguing part of China's lunar probe mission later this year, and could be a major boost for dreams that humans will one day live on the Moon. The insects, plants, potato seeds and arabidopsis—a small flowering plant belonging to the mustard family - will be taken to the Moon on board the Chang'e-4 lander and rover in December.

Aurora Station is being billed as the world's first luxury hotel in orbit. Slated to open in 2022, it'll charge guests $9.5 million.

Elon Musk's rocket company needs a license to broadcast from space, a requirement that is at once new and old.

In a study published today in Nature Astronomy, an international team of researchers announced the discovery of the most distant star ever observed. The team detected the blue supergiant star — which shone when the universe was just one-third its current age — with the help of both the Hubble Space Telescope and an observational phenomenon known as gravitational lensing.

As more countries and commercial companies invest in space programs, it is becoming harder to tell the difference between peaceful research projects and potentially destructive weapons, warns a new study by the Secure World Foundation. It cautions that an accelerating arms race in space raises huge concerns for the United States. The foundation on Wednesday released the report, “Global Counterspace Capabilities: An Open Source Assessment.”

These graceful arcs are a cosmic phenomenon known as an Einstein ring - created as the light from distant galaxies warps around an extremely large mass, like a galaxy cluster.

NASA’s Mars Reconnaissance Orbiter (MRO) has captured an incredible snapshot of the Matara Crater on Mars. The image, taken by the High Resolution Imaging Science Experiment (HiRISE) camera aboard the MRO, unveils spectacular gully formations on sand dunes inside the Martian crater.

Once again, a distant star know for its bizarre, unexplained light fluctuations has kicked into action, this time dipping in brightness more dramatically than ever.

Aside from that 19,000-pound Chinese satellite set to crash down this weekend, there are many more pieces of space junk in orbit.

Gwynne Shotwell said SpaceX would increase flight rate by 50 percent. It has.

A startup claims it will be able to place a single-module commercial space station into orbit by 2022, although the company faces multiple and significant technical and financial hurdles. Orion Span announced April 5 plans to develop what it calls the Aurora Station, a space station it says will be the “first luxury space hotel” in orbit. The company unveiled its plans at the Space 2.0 conference in San Jose, California.

Back in 1973, Concorde raced the Moon’s shadow along the the Tropic of Cancer

Astronomers for the first time precisely measured the distance to one of the oldest objects in the universe, a collection of stars born shortly after the big bang.

More than 100 million pieces of orbital debris are circling our planet. NASA has a strategy to cope on the rare occasion when the space junk falls to earth. @Enterprisenxt

Stephen Hawking died at age 76 on Wednesday, his family announced in a statement. The famed British physicist, whose theories on black hole radiation and cosmology transformed him into a household name, died peacefully in his Cambridge home. Toward the end of his life, Hawking strongly advocated for a future where humanity left the Earth and made new settlements on other planets.

Self-declared Flat Earth researcher and DIY steam rocket enthusiast “Mad” Mike Hughes has finally managed to prove the haters wrong about his ability to blast himself some 1,875 feet into the sky without being crushed or scalded to death, the Associated Press reported on Sunday.

Specifically, 100 planets like Earth: worlds of similar size, with a rocky surface, in the habitable zone, probably holding water, and orbiting a star like our Sun.

Titan might seem an unlikely place to for humans to build settlements, and maybe eventually colonize. After all, it is so far from the sun, and extraordinarily cold, and it's a long journey to get there (at present). But actually, if you set aside the difficulty of getting there, which we should overcome as our technology improves - it's got more going for it than you might think. This is an idea originally developed in some detail by Charles Wohlforth and Amanda Hendrix, authors of Beyond Earth: Our Path to a New Home in the Planets...

Scientists studying Jupiter using data and observations from the Juno spacecraft just released four new papers on their results, and I honestly can't say what's cooler: The science, or the jaw-dropping images.
