Once upon a time, the Milky Way died. It may have been several billions of years ago, but the stars in the sky paint a picture of the galaxy’s tumultuous history that has huge implications in galaxy evolution.
One poorly-worded tweet can cost a job in this day and age. A NASA intern learned this the hard way when she sent a profanity-laced tweet to another Twitter user who turned out to be an important NASA alum.
The vibrant purple night glow is a striking sight, but scientists are intrigued for another reason. STEVE is an entirely new phenomenon, different from the aurora events that it has previously been associated with.
Scientists finally confirm the presence of water ice on the moon's surface. A new study reveals evidence of water's existence in the darkest, coldest regions of the lunar poles.
Physicists have been trying to prove quantum entanglement for decades. An MIT team takes on the challenge, slipping past the 'freedom-of-choice loophole' by using light from quasars billions of years old.
The earliest galaxies in the entire universe are lying just outside the Milky Way, providing windows to an ancient time billions of years ago. A new study explains the formation of galaxies during the universe’s so-called cosmic dark ages.
Russia's satellite is officially a space apparatus inspector, but the United States alleged its abnormal behavior suggests a more aggressive nature. In a UN Conference, a State Department official says the Russian satellite could be a space weapon.
Is the Big Bang truly the start of everything? A team of scientists say no, suggesting that circles in the sky hint at a previous universe that came and was destroyed before the Big Bang.
Astronomers say that there are multiple mini-moons that orbit Earth. Mini-moons are asteroids that are temporary fixtures near Earth, getting caught in the planet's gravitational pull before its eventual escape.
Scientists say that there is a wall separating the solar system from the rest of the galaxy. The famous New Horizons spacecraft finally gets a glimpse of this boundary, according to a new study.
Astronaut Leland Melvin spoke candidly on Twitter about a strange 'alien encounter' he had on the Space Shuttle. It turns out, it's not just regular citizens who are on the lookout for extraterrestrial life.
NASA's new planet hunter kicks off its two-year mission with a comet photobombing a shot. In the resulting video, other astronomical events were also captured, including stellar flickering, Mars' reflection, and a host of asteroids on the move.
There's a stray planet floating aimlessly outside the solar system with no discernible orbit anchoring it there. This rogue planet is baffling scientists with its extreme mass and magnetic field.
It's another step in the alien hunt. Astronomers identify the group of planets that are best suited for life, narrowing down the field for the long-running search for extraterrestrial life.
