'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.

A Falcon 9 rocket delivered 51 more Starlink internet satellites into orbit Friday after launching from Vandenberg Space Force Base in California, adding to SpaceX’s global broadband network that reaches all seven continents.
Doomsday Glacier melting in Antarctica means terrible news for global sea level rise
The Thwaites Glacier in Antarctica is melting in unexpected ways that could lead to its rapid collapse, a new study has revealed.
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.
SpaceX launches 51 Starlink satellites, lands rocket on ship at sea (video)
SpaceX launched 51 of its Starlink internet satellites to orbit on Friday (Feb. 17), acing the first of two orbital missions the company has planned for the day.
When Neutron Stars Collide, the Explosion is Perfectly Spherical
Kilonovae are incredibly powerful explosions. Whereas regular supernovae occur when two white dwarfs collide, or the core of a massive star collapses into a neutron star, kilonovae occur when two neutron stars collide. You would think that neutron star collisions would produce explosions with all sorts of strange shapes depending on the angle and speed of the collisions, but new research shows kilonovae are very spherical, and this has some serious implications for cosmology.
The crescent moon meets up with Mercury tomorrow morning (Feb. 18)
The moon will meet up with the closest planet to the sun Mercury on Saturday, as the two celestial bodies meet in conjunction in the morning sky.
Watch SpaceX's Crew-6 astronaut flight live online
The first long-duration astronaut from the United Arab Emirates joins two NASA astronauts and one Roscosmos cosmonaut for a launch on Feb. 26. Here's how to watch.
Why are there so few 'hot Neptune' exoplanets?
There's apparently a dearth of close-orbiting Neptune-size planets in our galaxy, and two observation techniques are starting to explain why.
This Week's Sky at a Glance, February 17 – 26
Venus and Jupiter put on a dramatic show in twilight, as they creep toward each other for a March 1st conjunction. The crescent Moon passes though, almost kissing Jupiter on Wednesday the 22nd.
Small Asteroid Spotted Hours Before Demise
The swift detection of a small asteroid, and recovery of its surviving fragments, shows we’re getting better at spotting incoming objects.
1st private Launcher space tug fails after launching on SpaceX rocket
Space launch startup Launcher said its first spacecraft, which launched on a SpaceX rocket last month, has failed.
See a bright Venus and Jupiter hold a celestial meeting in the night sky this month
Venus and Jupiter should make for a very striking visual spectacle, no doubt attracting the attention of even those who don't give more than a casual glance at the night sky.
