Saturn's largest moon Titan casts a colossal shadow in breathtaking amateur portrait (photo)

Efrain Morales captured the image of Titan's shadow darkening Saturn on July 18, while the gas giant was over 800 million miles from Earth.

Collaboration or collapse: Why Earth observation must be a global mission

Satellites don't stop at borders and neither should science.

Webb traces details of complex planetary nebula

More than one star contributes to the irregular shape of NGC 6072 – Webb’s newest look at this planetary nebula in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicated mechanisms underway, as the star central to the scene approaches the very final stages of its life and expels shells of material, losing up to 80 percent of its mass.

Satellite Constellations Are Too Bright for Astronomy

The International Astronomical Union has recommended brightness limits for satellites, but companies aren't abiding by them.

'The Smithsonian Institution owns the Discovery.' Museum resists Trump's 'Big Beautiful Bill' plan to move space shuttle to Houston

The Smithsonian Institution says NASA relinquished full ownership of Space Shuttle Discovery, but Congress wants to force the vehicle's relocation.

'The most sophisticated radar we've ever built': US-Indian NISAR satellite launches to track tiny changes on Earth's surface (video)

The U.S. and India just launched NISAR, a powerful radar satellite that will be able to monitor changes in Earth's surface that are as small as a centimeter.

A troubling shift in Europe’s forest carbon balance

Europe’s forests play a crucial role in removing carbon dioxide from the atmosphere, but research led by the European Commission’s Joint Research Centre has found their capacity to absorb carbon dioxide has declined in the past decade.

Tracking Deep Space Probes With GEO Satellites Improves Uptime

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which also requires more powerful equipment, and positioning uncertainty that can affect the outcomes of measurements, especially in the outer reaches of the solar system. However, they can also be useful for a specific type of measurement called interferometry, where two systems a far distance apart can provide accurate location measurements to a third system - the same principle that GPS uses. A new paper looks at potentially using the same technique to track deep space probes rather than cars on a freeway and finds that, while it is around the same accuracy level, it is able to provide that same location data for more than double the amount of time.

James Webb Space Telescope finds giant, lonely exoplanets can build their own planetary friends without a parent star

Using the James Webb Space Telescope, astronomers have made the shock discovery that giant rogue exoplanets can grow their own planetary systems without needing a parent star.

Hubble Space Telescope spots rogue planet with a little help from Einstein: 'It was a lucky break'

Using the Hubble Space Telescope, astronomers have discovered a new rogue planet that was orphaned from its home planetary system. The discovery was possible with a little luck and some help from Einstein.

Greenland subglacial flood bursts through ice sheet surface

Using data from several Earth-observing satellites, including ESA’s CryoSat and the Copernicus Sentinel-1 and Sentinel-2 missions, scientists have discovered that a huge flood beneath the Greenland Ice Sheet surged upwards with such force that it fractured the ice sheet, resulting in a vast quantity of meltwater bursting through the ice surface.

SpaceX launches 28 Starlink satellites on a Falcon 9 rocket from Florida

A SpaceX Falcon 9 rocket carrying 28 Starlink satellites was launched from Cape Canaveral Space Force Station in Florida on Tuesday, July 29, 2025.

Lava Existed in the Moon's Subsurface Longer than Previously Thought

According to the prevailing theory of how the Moon formed, it all began roughly 4.5 billion years ago when a Mars-sized object (Theia) collided with a primordial Earth. This caused both bodies to become a molten mass that eventually coalesced to form the Earth-Moon System (aka. The Giant Impact Hypothesis. This theory also states that the Moon gradually cooled from the top down, with the crust solidifying and arresting lava flows early in its history. However, recent findings from samples obtained by China's Chiang'e-5 probe indicate that lava existed at shallower depths longer than previously thought.

AI Uncovers Subsurface Entrances on the Moon

How can artificial intelligence (AI) be used to locate lunar pits and skylights, which are surface depressions and openings, respectively, that serve as entrances to lava caves and lava tubes? This is what a recent study published in Icarus hopes to address as an international team of researchers investigated using machine learning algorithms to more efficiently identify pits and skylights on lunar volcanic regions (lunar maria) of the Moon. This study has the potential to help researchers develop new methods in identifying key surface features on planetary bodies that could aid in both robotic and human exploration.

Australia's 1st orbital rocket, Gilmour Space's Eris, fails on historic debut launch

Gilmour Space made history today (July 29), conducting the first-ever orbital launch attempt with an Australian-built rocket. That vehicle, named Eris, didn't get very far.

SpaceX moves Starship to launch pad for testing ahead of Flight 10 (photos)

SpaceX has moved its Starship spacecraft to the launch pad for testing ahead of the vehicle's 10th flight, which is expected to take place next month.

The 1st trailer for James Cameron's 'Avatar: Fire and Ash' promises a stunning three-way battle for the future of Pandora (video)

James Cameron's third Avatar movie is turning the rules upside down, introducing a nefarious Na'vi clan as the human invaders go all-out.

Watch India and NASA launch the powerful NISAR Earth-observing satellite on July 30

India will launch the NISAR Earth-observing spacecraft, a joint effort of ISRO and NASA, on July 30, and you can watch the action live.

Waterworld we live in: 30 years on from 'Waterworld', Kevin Costner's watery 'Mad Max' that's better than you remember

Unfairly dismissed as a flop on release, 'Waterworld' is a spectacular example of the '90s action genre. If only they didn't give him gills…
