Astronomers Around the World Are Training in Case a Giant Asteroid Threatens Earth

On 12 October 2017, a 20-metre asteroid passed just 50,000 kilometres (31,000 miles) from Earth. For weeks, dozens of astronomers from labs around the world mobilised, measuring everything they could about the asteroid in preparation for an impact. Read More >>

It Looks Like There’s a Second, Bigger Impact Crater Under Greenland’s Ice

Scientists have spotted a potential asteroid crater in Greenland just 114 miles away from another one announced a few months ago. But the newest crater is even larger—it would be the 22nd largest on Earth. Read More >>

Gaze in Awe at Hubble’s Most Detailed View of the Triangulum Galaxy

Usually when astronomers talk about our neighbouring galaxy, they’re talking about Andromeda, which is a cozy 2.5 million light-years away. But just a little farther – okay, 500,000 light-years farther – is another spiral galaxy, the third largest in our local group. Hubble has just released its most detailed view yet of that galaxy, which is known as Triangulum (can you see why?). Read More >>

Telescope Drama Could Thwart the Hunt for Extraterrestrial Life

For nearly 20 years, NASA has been planning and constructing a telescope unlike any ever built before: the James Webb Space Telescope. It will change the way scientists see the most distant galaxies and intensify the hunt for extraterrestrial life; it will answer outstanding questions about the birth and death of stars and planets. It is the future of astronomy—but it’s causing trouble. JWST’s high price and decade of delays could stymie the development of future telescopes, impacting the course of astronomy for the next 30 years. Read More >>

Watch a Famous Supernova Change Over 25 Years

Perhaps the most important supernova of the modern era is SN 1987A, the closest supernova to Earth since the invention of the telescope. Scientists have been observing the explosion’s remnants since the 1987 event. Read More >>

Our Galactic Neighbours Once Collided, New Observation Suggests

Should you find yourself in the southern hemisphere beneath dark skies, look up: You’ll see two faint, glowing smudges beside the vast, glowing trail of our Milky Way galaxy. These two Magellanic Clouds are galaxies, too, though smaller ones orbiting our own. And some time in the past, perhaps back in the dinosaur days, those two clouds may have collided. Read More >>

Discovery of ‘Goblin’ Solar System Object Bolsters the Case for Planet Nine

Astronomers have discovered an object, dubbed “the Goblin,” in the outer reaches of the Solar System. The dwarf planet never gets any closer to the Sun than 6 billion miles, but experts say its orbital configuration points to the existence of a much larger, more distant planet —the elusive Planet Nine.

New Particle Could Explain ‘Unusual’ Antarctic Weather Balloon Detection

A weather balloon in Antarctica spotted what looked like a high-energy particle from outer space striking the ice back in 2006. Except the particle didn’t hit from above—it somehow travelled all the way through the planet. Eight years later, it happened again. Read More >>
