United Launch Alliance is back at the launch pad for another attempt to launch the first production satellites for Amazon’s Project Kuiper satellite internet constellation.

It's nearly impossible to overstate the effect supermassive black holes have on their host galaxies. When actively accreting matter, they release colossal amounts of energy as winds, jets, and radiation that shape their surroundings. But stellar mass black holes also shape their surroundings with energetic jets.

A Venus lander launched by the Soviet Union in 1972 has been predicted to fall back to Earth some time in May.

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

Using the Dark Energy Camera astronomers have found a packed stellar nursery of infant stars in the dark nebula in the 180-light-year-wide Circinus West molecular cloud.

Nothing wows new observers like seeing Saturn for the first time. I always check out the ringed planet if it's visible, and telescopes down the line at any star party will invariably be pointed Saturn-ward to a chorus of ‘oh’s’ and ‘ah’s’…. but 2025 gives you another reason to gaze at Saturn, as its largest moon Titan completes a series of rare shadow transits.

This fantastic Lego set makes a great display piece but with movable limbs, it's fun for fueling youngsters' Marvel Universe imagination and it's rarely discounted, so grab it while you can.

March was a busy month for climate disasters in the U.S., as the nation endured tornado outbreaks, raging wildfires, and record-setting heat.

The Atomic Clock Ensemble in Space (ACES), ESA’s state-of-the-art timekeeping facility, is now installed on the Columbus laboratory of the International Space Station. This still image, captured by external cameras on the Station, shows ACES after installation. For 25 years, cameras on the Station have documented activities in orbit, providing real-time views of operations like this one – a rare and remarkable perspective from space. 

Europe's Sentinel-1 satellites captured radar images of Myanmar before and after a magnitude 7.7 earthquake struck on March 28, revealing significant ground movement.

The first bits of data have come back from NASA's EZIE cubesat mission, which aims to solve some mysteries surrounding the "auroral electrojet" phenomena in Earth's atmosphere.

Using the James Webb Space Telescope, scientists have found an extremely ancient galaxy piercing through a thick blanket of cosmic fog in the distant universe.

After years of careful design and preparation, ESA’s Earth Explorer Biomass satellite is set for launch tomorrow, 29 April at 11:15 CEST, aboard a Vega-C rocket from Europe’s Spaceport in French Guiana.

SpaceX launched its 250th dedicated Starlink mission on Sunday night (April 27), sending 23 of the broadband satellites to low Earth orbit.

NASA's Psyche mission launched in 2023 and has now successfully demonstrated that laser technology can transmit high-bandwidth data across millions of kilometres in space, making it promising for communications from Mars. However, researchers simulating Martian conditions found that while this optical communication works well under normal circumstances, performance degrades during dustier periods and fails completely during global dust storms.

NASA researchers got a rare chance to study Uranus' atmosphere and rings this month, when the ice giant passed between Earth and a distant star, creating a "stellar occultation."

The 2005 cult classic was pivotal to giving the Grand Army of the Republic faces and voices before George Lucas and Dave Filoni went deeper.

The Trump administration has canceled the New York City lease of the Goddard Institute for Space Studies, a leading NASA climate-studying organization.

Venus, Saturn and dim Neptune will form a planetary triangle in the pre-dawn sky on April 28, with Mercury hovering on the periphery.

What kind of spacecraft can be used to explore and study the subsurface lunar environment? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as an international team of researchers discussed the benefits of a mission concept called LunarLeaper, which will be designed to traverse and analyze the various aspects of the lunar subsurface environment, including moon pits and lava tubes.

Since the invention of the telescope, astronomers have been hunting for objects in our Solar System in particular and more recently, for the theorised 9th planet. Observations of Kuiper Belt objects suggest a large object might be lurking in the depths of the Solar System but to date, it hasn’t been directly observed. A team of researchers have analysed infrared sky surveys and found 13 objects that matched the estimated flux and motion of Planet Nine! Further analysis ruled out 12 leaving a single object. Is this Planet Nine?
