We put the Sony FE 50mm f/1.4 G Master prime lens through its paces to see if this premium-performance optic justifies a premium price tag.

Astronomers have long voiced concerns about Starlink's satellite constellation interfering with observations of the universe, and a new survey by Curtin University confirms those fears.

What could we choose as the seven most remarkable celestial objects visible either with our eyes or with a small telescope?

The glowing light shows the intricate details that make this cutting-edge telescope work.

Looking at dunes and other rock formations on both Earth and Mars can tell scientists the environmental conditions that created them

The US West Coast is the world's worst mega-drying region.

A red supergiant star is surrounded by a sphere of dust and gas so large there is no known explanation for what produced it

Earlier this year, astronomers reported possible evidence of life on another planet – but new observations from JWST suggest the apparent biosignature isn’t there after all

Ultimately, we do not understand where glitches come from or exactly what's going on inside pulsars.

Nebulas are perhaps as famous for being identified

The cast of "Star Trek: Strange New Worlds" has to cover a wide range of dramatic genres, aided in part by the show's ample stockpile of wigs.

A new behind-the-scenes featurette from Hulu's upcoming 'Alien: Earth' show why the series will be pure nightmare fuel.

The European company Eos X Space has acquired Space Perspective, one of its key rivals in the nascent field of stratospheric balloon tourism.

Satellite data allows meteorologists to keep track of the location, structure and intensity of severe weather, helping to keep people safe. Now they're losing access to these satellites.

Mars will be less than four degrees from the crescent moon around sunset on July 28.

After an early morning launch from Florida, SpaceX sent another 24 Starlink satellites into orbit on a Falcon 9 launch from Vandenberg Space Force Base in California early on Sunday, July 27, 2025.

In the young V883 Orionis system, ALMA observations have revealed signatures of complex organic compounds such as ethylene glycol and glycolonitrile – potential precursors to amino acids, DNA, and RNA. These findings indicate that the building blocks of life may not be limited to local conditions but could form widely throughout the Universe under suitable circumstances.

What can brine (extra salty) water teach scientists about finding past, or even present, life on Mars? This is what a recent study published in Communications Earth & Environment hopes to address as a researcher from the University of Arkansas investigated the formation of brines using 50-year-old data. This study has the potential to help researchers better understand how past data can be used to gain greater insights on the formation and evolution of surface brines on the surface of Mars.
