The scientists behind NASA’s largest and most powerful space telescope ever built are bracing for potentially crippling budget cuts, and the observatory is only halfway through its primary mission. The team overseeing NASA’s James Webb Space Telescope (JWST) has been directed to prepare for up to 20% in budget cuts that would touch on every … Read more
As far as we can tell, life needs water. Cells can’t perform their functions without it. Some have suggested that other exotic liquids, like liquid methane, could do the job on worlds like Saturn’s moon Titan. That idea is highly speculative, though. So, it makes sense that NASA is launching a spacecraft dedicated to the … Read more
The sun, for all its glitz, tends to hide behind a veil of mystery. For instance, its outer atmosphere, the corona, appears to be hotter than its surface — like, way hotter — and scientists aren’t sure why. There’s also a big puzzle concerning how the solar wind, which is a stream of charged particles … Read more
In August 2018, NASA’s Parker Solar Probe (PSP) began its long journey to study the Sun’s outer corona. After several gravity-assist maneuvers with Venus, the probe broke Helios 2‘s distance record and became the closest object to the Sun on October 29th, 2018. Since then, the Parker probe’s highly elliptical orbit has allowed it to … Read more
A NASA spacecraft is about to give astronomers an epic early Christmas present with the closest ever flyby of the sun on Dec. 24, but if you’re wondering exactly when the ambitious solar encounter will occur, don’t worry. We’ve got you covered. The NASA spacecraft, called the Parker Solar Probe, is on course for what … Read more
In 2018, NASA mission planners selected the Jezero Crater as the future landing site of the Perseverance rover. This crater was a natural choice, as it was once an ancient lake bed, as evidenced by the delta fan at its western edge. On Earth, these features form in the presence of flowing water that gradually … Read more

NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has helped astronomers better understand the shapes of structures essential to a black hole – specifically, the disk of material swirling around it, and the shifting plasma region called the corona. The stellar-mass black hole, part of the binary system Swift J1727.8-1613, was discovered in the summer of 2023 … Read more
The Optical Telescope Assembly for NASA’s Nancy Grace Roman Space Telescope was recently delivered to the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. (Image credit: Future) Scientists working on NASA’s Nancy Grace Roman Space Telescope have achieved a significant milestone in assembling the next-generation observatory, which aims to address … Read more
