Some 2 to 3 billion years after the big bang most galaxies went through a growth spurt, forming stars at a rate hundreds of times higher than we see in our own galaxy today. NASA’s Nancy Grace Roman Space Telescope promises to bring new insights into the heyday of star formation.
NASA announced Friday that the Psyche asteroid mission – the agency’s first mission designed to study a metal-rich asteroid – will not make its planned 2022 launch attempt.
The NASA/ESA Hubble Space Telescope captured this massive galaxy cluster, called Abell 1351, with its Wide Field Camera 3 and Advanced Camera for Surveys. Abell 1351 lies in the constellation Ursa Major in the northern hemisphere.
The COVID-19-related lockdowns granted scientists an unexpected and detailed glimpse as to how human activities impact atmospheric composition. Two recent studies, one focusing on nitrogen oxide and the other examining CO2 concentrations, were able to detect the atmospheric ‘fingerprint’ of the... Read More
You may not be familiar with the term “colloids;” yet, they are a part of our everyday lives. Colloids are mixtures of microscopic particles suspended in fluids — substances that are part solid, part liquid. In our daily life, colloids are found in everything from toothpaste to ketchup, paint to... Read More
NASA's APOD has been honored by the International Astronomical Union for decades of outreach.
To human eyes, the night sky between the stars appears dark, the void of space. But X-ray telescopes capture a profoundly different view. Like a distant firework show, our images of the X-ray sky reveal a universe blooming with activity. They hint at yet unknown cosmic eruptions coming from... Read More
This star-studded image shows the globular cluster Terzan 9 in the constellation Sagittarius, toward the center of the Milky Way.
In extreme ultraviolet light, the Sun resembles a rumpled ball of yarn. It teems with giant radiant arcs known as coronal loops soaring through the Sun’s corona. However, some scientists now think these loops may be an optical illusion.
Both rocky and icy bodies were identified among the debris on the surface of a white dwarf star
An instrument on the space station documented how built and natural surfaces responded to record heat in Las Vegas.
A young pulsar is blazing through the Milky Way at a speed of over a million miles per hour. This stellar speedster, witnessed by NASA’s Chandra X-ray Observatory, is one of the fastest objects of its kind ever seen. This result teaches astronomers more about how some of the bigger stars end their... Read More
