One definition for goulash, according to the Merriam-Webster dictionary, is a mixture of heterogeneous elements, or jumble. This 2017 image of galaxy Arp 299 is just that. Arp 299 is a system located about 140 million light-years from Earth, containing two galaxies that are merging, which has created a partially blended mix of stars from each galaxy. Data fr...
In this view from aboard the SpaceX Crew Dragon Endeavour, a pair of the International Space Station’s main solar arrays seemingly drape across the Earth’s horizon as the orbital lab soars 271 miles above the south Atlantic in between Argentina and South Africa. Earth is a pale, blue dot when seen from space because our home planet is 71 percent ...
NASA astronaut Mark Vande Hei works on Celestial Immunity, an investigation of how gravity affects immune response, potentially supporting development of new vaccines and drugs to prevent and treat existing and emerging human diseases. Celestial Immunity evaluates the effects of gravity on functional immune response and the role of age in regulating immune p...
Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory, as shown in this image from March 2021. This result may help scientists learn more about this enigmatic ice giant planet in our solar system. Uranus is the seventh planet from the Sun and has two sets of rings around its equator. The planet, which has fou...
NASA Administrator Bill Nelson talks to the agency’s workforce during his first State of NASA event Wednesday, June 2, 2021, at NASA Headquarters Mary W. Jackson Building in Washington. Nelson remarked on his long history with NASA, and among other topics, discussed the agency’s plans for future Earth-focused missions to address climate change and a robotic ...
When NASA digital strategist Andres Almeida joined Twitter in 2009, one of the first accounts he followed was NASA. “I knew they were doing NASA ‘Tweetups’ (now called Socials) where members of the public could apply, go behind the scenes of a NASA facility and potentially attend a launch. “I was selected for the STS-135 Tweetup — the final launch of t...
Astronomers continue to develop computer simulations to help future observatories better home in on black holes, the most elusive inhabitants of the universe. Though black holes likely exist abundantly in the universe, they are notoriously hard to see. Scientists did not capture the first radio image of a black hole until 2019, and only about four dozen blac...
This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail. This detail is possible using Hubble’s Wide Field Camera 3...
