A new type of glitch in the LIGO gravitational wave detector was identified by users. The glitch causes a distinctive image that looks like a flying saucer.
Researchers using the Chandra X-ray Observatory are studying the galaxy cluster Abell 1775 for signs of a past collision with another cluster. Galaxy clusters are the most massive known structures in the universe, and their collisions release immense amounts of energy.
Researchers using European Southern Observatory’s Very Large Telescope captured colorful images of several nearby galaxies. The observations give scientists insight into what causes stars to form.
The Hubble space telescope resumed observations following a computer error earlier in 2021. Its first targets included a set of unusual galaxies — one with extended spiral arms and another pair colliding.
Researchers captured the highest resolution images ever of a black hole ejecting radiation jets. Scientists don’t yet understand what causes the jets to erupt.
Researchers confirmed that the Xerces blue butterfly was a distinct species before it went extinct. Before, there was some debate over whether the butterfly, the first known insect destroyed by human development, was actually part of another species.
NASA’s Perseverance rover began its search for evidence of ancient life on Mars. The rover is using X-rays, ultraviolet light, and photos to analyze rocks on the planet’s surface.
Researchers found evidence that pterosaurs may have been able to fly just after hatching. Newly hatched pterosaurs are thought to have been more agile but weaker than adults.
