An enormous supercluster made up from over 20 individual galaxy clusters hiding behind our dusty Milky Way is even larger than astronomers had thought, affecting the motion through space of all the galaxies and galaxy clusters in our corner of the cosmos.
The Vela Supercluster was discovered in 2016 thanks to a team led by Renée C. Kraan-Korteweg of the University of Cape Town in South Africa.
The peak of the Eta Aquarid meteor shower is almost here! Read on to discover the best time to spot the fast-moving shooting stars as Earth barrels through the debris trail shed by Halley’s Comet.
When are the Eta Aquarids most active?
In 2026, the Eta Aquarids are active…
In its infancy, the universe had a bit of an identity crisis.
For the first few hundred million years, the vast cosmic gas between galaxies was primarily a chilly, dense affair. But then, it seemed to wake up, deciding to get all warm and fuzzy.
This strange shift in the…
The June full moon occurs at 7:57 p.m. EDT (2357 GMT) on June 29. That’s when the lunar disk will pass opposite the sun in Earth’s sky, appearing fully lit by the sun’s rays.
This month’s full moon is also known as the “Strawberry Moon,” reflecting the time of year when Native American tribes harvest the ripened fruit. It is also the first full moon of summer, following soon after the…
NASA has released a pair of sweeping new panoramas from its two active Mars rovers, Curiosity and Perseverance, offering a vivid look at how dramatically different regions of the Red Planet can be — and how each mission is uncovering a distinct chapter of Martian…
The May full moon rises at sunset tonight! Here’s what you need to know as the full “Flower Moon” takes to the spring sky on May 1 and when to look out for a rare “Blue Moon” later in the month.
The moon will be 100% illuminated at 1:23 p.m. EDT (1723 GMT) on May 1…
COLORADO SPRINGS, Colorado — Asteroid Apophis is set to whisk by Earth in 2029 and serve as a wake-up call for getting our planetary defense act together.
Astronomers have shown that the huge chunk of extraterrestrial real estate will not hit Earth in 2029, but will come closer to Earth than our geostationary communications satellites. Radar measurements estimate Apophis is roughly 1,500 feet…
Looking for a star projector that’ll bathe a whole room in a cosmic display? At just $25, you can’t go wrong with this Fliti Galaxy Projector, but it’s a limited time deal so you’ll have to hurry.
Sick of star projectors disappointing you with their displays? Then…
NASA astronaut Don Pettit is showing off his pride and joy: a potato named “Spudnik.”
In their very minimal “free time,” astronauts aboard the International Space Station generally play instruments, make art, take photos, and more. But Pettit spent his time making…
A new citizen science project invites the public to scan never-before-seen images from the Euclid Space Telescope in search of galaxies bending spacetime.
Led by the European Space Agency (ESA), the initiative, called Space Warps, uses data from Euclid to crowdsource the search for rare cosmic distortions known as gravitational lenses. These occur when massive foreground objects such as galaxies…
