Surprise! Colliding neutron stars create perfectly spherical 'kilonova' explosions
Kilonova explosions created when neutron stars collide and merge are perfectly spherical, not flattened discs as previously expected, a new study suggests.
ESA is Building an Early Warning System for Dangerous Asteroids
The European Space Agency is working on a new mission that would act as an early warning system for dangerous, hard-to-see asteroids. Called NEOMIR (Near-Earth Object Mission in the InfraRed), the spacecraft would orbit between the Earth and the Sun at the L1 Lagrange Point, finding space rocks that otherwise get lost in the glare of the Sun.
New auroras detected on Jupiter's four largest moons
The four largest moons of Jupiter - Io, Europa, Ganymede, and Callisto - have newly discovered auroras that can be seen in visible light.
Russian Progress cargo ship undocks from space station despite coolant leak
A robotic Russian cargo ship stricken by a coolant leak undocked from the International Space Station late Friday (Feb.17) while cosmonauts snapped photos of it looking for signs of damage.
Leonardo da Vinci's lost sketches show early experiments to understand gravity
Leonardo da Vinci's centuries-old sketches reveal he may have understood key aspects of gravity long before Galileo, Newton and Einstein.
Instrument on NASA's Parker Solar Probe switches off unexpectedly
One of the instruments on NASA's Parker Solar Probe powered down unexpectedly last weekend, but the mission team expects it to come back online soon.
Sun unleashes massive X2-class solar flare during geomagnetic storm watch (video)
A massive solar flare erupted from the sun on Friday (Feb. 17) as the Earth was under a geomagnetic storm watch from flares earlier in the week.
Watch a comet make its 1st and final pass by the sun this weekend
The comet C/2022 A2 (Pan-STARRS) will pass close by the sun on Sunday (Feb. 19), making its first and likely final approach to our star.

'Fantastic Voyage' and 'One Million Years B.C.' star Raquel Welch dies at 82
Actress Raquel Welch passed away at the age of 82 after a long and illustrious career that includes science fiction classics such as "Fantastic Voyage" and "One Million Years B.C."
Are Black Holes the Source of Dark Energy?
By the 1920s, astronomers learned that the Universe was expanding as Einstein’s Theory of General Relativity predicted. This led to a debate among astrophysicists between those who believed the Universe began with a Big Bang and those who believed the Universe existed in a Steady State. By the 1960s, the first measurements of the Cosmic Microwave Background (CMB) indicated that the former was the most likely scenario. And by the 1990s, the Hubble Deep Fields provided the deepest images of the Universe ever taken, revealing galaxies as they appeared just a few hundred million years after the Big Bang.
Galaxies Aren’t Just Stars. They’re Intricate Networks of Gas and Dust
Astronomers have studied the star formation process for decades. As we get more and more capable telescopes, the intricate details of one of nature’s most fascinating processes become clearer. The earliest stages of star formation happen inside a dense veil of gas and dust that stymies our observations.
Rare red auroras explode over America's and Europe's north, and more are on their way
A stream of solar plasma arrived at Earth last night, triggering rare red aurora displays across Canada, northern U.S. and Europe. And more is on its way.
Watch live: Russian cargo ship set to depart space station after coolant leak
Russian cosmonauts will try to take pictures of the location where coolant leaked out of a Russian Progress cargo ship earlier this month when the supply freighter departs the International Space Station Friday night, as scheduled, to head for a destructive re-entry over the Pacific Ocean.

Mystery object shot down over Yukon may have been harmless 'pico balloon'
The object blasted out of the sky over the Yukon on Feb. 11 may have been an amateur radio pico balloon — specifically, a 33-inch-wide one called K9YO-15.
This is Your Brain on Spaceflight
When you go to space, it’s going to change your brain. Count on it. That’s because space travelers enter microgravity, and that challenges everything the brain knows about gravity. The experience alters their brain functions and “connectivity” between different regions. It’s all part of the ability of our brains and nervous systems to change in response to changes in the environment, or because of traumatic brain stress or injuries.
James Webb Space Telescope spies baby stars dancing in swirling gas and dust (photos)
The James Webb Space Telescope spied the arms of barred spiral galaxy NGC 1433 teeming with young stars that are affecting the clouds of gas and dust around them.
