A new study shows that most of the inner rocky planets in the solar system once orbited the sun in perfect alignment. (Image credit: SCIEPRO/Getty Images) The solar system’s four terrestrial planets, including Earth and a long-lost world, likely formed…
NASA has released a collection of nine new images created by the Chandra X-ray Observatory using the Hubble and JWST telescopes. This new series of images from NASA’s Chandra Space Telescope, which was launched in 1999, shows what different objects…
Scientists have created a stunning animation showing the suspected intermediate-mass black hole HLX-1 tearing apart a star, causing a bright tidal disruption event. (Image credit: NASA, ESA, Ralf Crawford (STScI)) Astronomers believe they have discovered an extremely rare type of…
The Sun’s gravitational pull extends out to more than 160 times farther than Neptune’s. (Image credit: Vadim Petrakov via Shutterstock) Is there a huge, undiscovered planet at the edge of the solar system? The concept has been around since Pluto…
Illustration of a giant molecular cloud (Image credit: NSF) Astronomers have discovered a colossal cloud of gas and dust that stretches for as much as 200 light years and is hidden in a poorly studied region of the Milky Way.…
(Image credit: NSF/AUI/NSF NRAO) A team of scientists led by the National Science Foundation’s Green Bank Observatory (NSF GBO) recently identified an unusually rare object known as a long-period radio transient (LPT), designated CHIME J1634+44. These objects resemble rotating radio…
These images from the Solar Dynamics Observatory show the Moon’s path across the Sun on July 25, 2025. (Image credit: NASA/SDO and the AIA, EVE, and HMI science teams) A near-Earth spacecraft has just witnessed a rare event: a lunar…
(Image credit: NASA/JPL) A small meteorite is changing researchers’ views on the origins of our solar system. New evidence from a sliver of the Northwest Africa 12264 meteorite, a 50-gram (1.8-ounce) chunk of space material thought to have formed in…

Sunspots captured in 2014. Spots this size are difficult to detect on distant stars because they cause brightness variations that are too small to be interpreted as noise. However, a new approach may have just revealed a large spot on…
