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 from April 19 to May 28 and come to a broad peak overnight on May 5-6. Your best chance to spot shooting stars will be during…
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…
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 history.
The newly released images showcase starkly different landscapes, captured thousands of miles apart by the two robots, which…
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…
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.

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…
What is quantum gravity? Scientists think it could explain the beginning of our universe
April 30, 2026
Scientists have redefined gravity to explain the Big Bang and perhaps change our picture of the earliest moments of the cosmos. This new framework of “quantum gravity” may explain aspects of the Big Bang that Albert Einstein’s 1915 theory of gravity, general relativity, fails to account for — maybe even doing away with the challenging concept of a singularity existing prior to the dawn of…
