The discovery could explain why younger stars seem to have more lithium than the Big Bang theory says they should have.

The Orzorz Star Projector, the best viral model and best under $100, is now 25% off this Amazon Prime Day in one of the best star projector deals.

At the 246th American Astronomical Society meeting in Alaska last month, scientists discussed how Trump's budget cuts could affect operations for the Hubble Space Telescope and JWST.

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and molecules, and laser-wielding scientists are revealing the action

Aboard the International Space Station, Ayers pulls out physics research hardware inside the Microgravity Science Glovebox

We've rounded up the best Amazon Prime Day drone deals as the retailer's annual sales event kicks off on July 8 and runs through to July 11.

The Sony A7 III is $1380 from Walmart on this anti-Prime deal and is a huge $118 cheaper than Amazon!

Canadian company NordSpace hopes to be the first in the country's history to launch an orbital rocket from Canadian soil. They've got the support of ProtoSpace, a specialized aerospace manufacturing provider hoping to support Canada's budding space industry.

What do you see when you look into this sky?

How do galaxies like ours continue producing stars long after they should have used up their star-forming gas. Somehow, an external gas source must find its way into the galaxy. New research has found evidence of gas clouds that found their way into a spiral galaxy, likely fueling continued star formation.

The beautiful supernova remnant looks a little different from other examples of stars that detonated in the past. And it should, because according to astronomers, the star that met its end exploded twice. It was a white dwarf in its former life, pulling material from a binary companion, creating the perfect conditions for a Type 1a supernova. It accumulated a blanket of helium, which exploded first, triggering a second detonation at the core of the star.

Astronomers used the JWST to examine M82, a nearby starburst galaxy. M82 is forming stars at a prodigious rate due to its interactions with its neighbour, M81. It produces thousands of solar masses of stars per year, much more than the Milky Way.

China's asteroid probe turned its cameras back towards the Earth and Moon, capturing an image of our home planet on May 30, 2025. The image was taken when the spacecraft was about 590,000 km away, speeding towards asteroid 2016HO3, where it will retrieve a sample and bring it back to Earth before carrying on to main-belt comet 311P. The spacecraft has been in flight for 33 days and is now over 12 million kilometers from Earth.

According to the latest studies led by Heidelberg University astronomers, low-mass stars quite often host Earth-like planets. Data collected as part of the CARMENES project were the basis of this finding. By analyzing the data, an international research team succeeded in identifying four new exoplanets and determining their properties.

A newly discovered object may give astronomers an opportunity to study an interstellar visitor like never before. The object (A11pl3Z) is currently at +18th magnitude, moving slowly along the border of the constellations Serpens Cauda and Sagittarius, right near the galactic plane. The object was captured on July 2nd by the Deep Random Survey remote telescope in Chile. The Asteroid Terrestrial-impact Last Alert System (ATLAS) based in Rio Hurtado made the discovery on July 1st. Sam Deen soon backed this up with pre-discovery images from worldwide ATLAS sites in Chile, Hawaii and South Africa from June 25-29.

A pair of Japanese weather satellites took a break from monitoring Earth weather to sneak a peek at Planet Venus. Despite the fact that it's relatively tiny, and millions of kilometers away, they were able to detect changes in Venus' cloud-top temperatures and see patterns and structure in its upper atmosphere. There are long-term trends on Venus that these long-lasting satellites will be able to study, beyond the timeframe of a shorter mission.

For folks in the United States, July evenings mean 4th of July fireworks. While you’re waiting for the show, be sure to watch for the most elusive of the planets as twilight falls, as Mercury shines at its very best for 2025. If you’ve never seen the innermost world before, now is a good time to try. This is because Mercury reaches greatest elongation, or its greatest point from the Sun as seen from our Earthly vantage point later this week.

The U.S. military is suspending its efforts to secure a small Pacific island as the test landing site for a new program using rockets to rapidly deliver cargo anywhere on Earth.
