In this image that astronaut Scott Kelly posted to Twitter on Aug. 9, 2015 during his #YearInSpace captures all the the places humans dwell – the Earth, the International Space Station and the Milky Way. His accompanying caption read: “Day 135. #MilkyWay. You’re old, dusty, gassy and warped. But beautiful. Good night from @space_station! #YearInS...
On Sunday, April 18, 2021, NASA astronauts Megan McArthur and Shane Kimbrough, ESA (European Space Agency) astronaut Thomas Pesquet, and JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, wearing SpaceX spacesuits, are seen as they prepare to depart the Neil A. Armstrong Operations and Checkout Building for Launch Complex 39A during a dress...
Spectacular jets are powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A. The jets shoot through space for millions of trillions of miles. This image, taken by the Hubble Telescope, was originally released in November 2012. Learn more about black holes: NASA’s Field Guide to Black Holes Image...

This false-color image, taken by the Chandra X-Ray Observatory in 2012, shows an extraordinary outburst from a black hole – where its X-ray output increased at least 3,000 times – in the galaxy M83. Chandra observed what is called a ULX, or ultraluminous X-ray source. The remarkable behavior of this ULX in M83 provides direct evidence for a population of old...
In April 2019, a black hole and its shadow were captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation. A black hole is an extremely dense object from which no lig...
When space shuttle Columbia took to the skies on its maiden voyage on April 12, 1981, a new era of spaceflight took wing. Space Transportation System-1, or STS-1, was the first of its kind when it lifted off from NASA Kennedy Space Center. In this image, the reusable orbiter, its two fuel tanks and two solid rocket boosters has just cleared the launch tower....
Mary W. Jackson, NASA’s first black female engineer, was born April 9, 1921. Jackson earned degrees in mathematics and physical sciences in 1942. She landed a job at the Langley Memorial Aeronautical Laboratory’s segregated West Area Computing section in 1951, reporting to the group’s supervisor Dorothy Vaughan and eventually working alongside Katherin...
A sea of dark dunes, sculpted by the wind into long lines, surrounds Mars’ northern polar cap and covers an area as big as Texas. In this false-color image, areas with cooler temperatures are recorded in bluer tints, while warmer features are depicted in yellows and oranges. Thus, the dark, sun-warmed dunes glow with a golden color. This image covers a...
Today is World Health Day and NASA’s Earth Science Division is using information from our Earth-observing satellites, surface sensors, and computer-based datasets to study the environmental, economic, and societal impacts of the COVID-19 pandemic and to determine whether environmental factors influence the spread of the virus. While scientists around t...
