Iowa native astronaut Raja Chari was selected by NASA to join the 2017 Astronaut Candidate Class. He is a graduate of the U.S. Air Force Academy with bachelor’s degrees in astronautical engineering and engineering science, and later earned a master’s degree in aeronautics and astronautics from Massa […]
Several hundred million years ago, two galaxy clusters collided and then passed through each other. This mighty event released a flood of hot gas from each galaxy cluster that formed an unusual bridge between the two objects. This bridge is now being pummeled by particles driven away from a supermas
NASA astronaut Ricky Arnold takes an out of this world “space-selfie” while conducting a spacewalk on March 29, 2018. Before he joined the Astronaut Corps, Arnold was a teacher, who taught all over the world from Malaysia to Romania. As an astronaut he served on STS-119 and aboard the In
Blooming roses at the Armstrong Flight Research Center (AFRC) highlight the Bell X-IE aircraft mounted in front of the main building at the center. The X-1E was one of the first supersonic aircraft and was the last of the X-1 series of aircraft. It was last flown in November 1958 and now resides at
In this image from 1969, Life Detection Systems branch chief Vance Oyama operates a specially designed soil distribution system, used for dispersing the lunar soil in equal amounts to thousands of petri dishes as part of the lunar biological experiments performed at NASA’s Ames Research Center.

This 2018 composite of the Crab Nebula was made with data from the Chandra X-Ray Observatory (blue and white), Hubble Space Telescope (purple), and Spitzer Space Telescope (pink). The star that exploded to create the Crab Nebula was first seen from Earth in 1054 A.D. Since its launch in 1999, Chandr
It’s #TeacherAppreciationWeek and teachers and space travel go hand-in-hand. Teacher-turned-astronaut Joe Acaba taught one year of high school science at Melbourne High School, Florida, and four years of middle school math and science at Dunnellon Middle School, Florida. As an astronaut, Acaba

He also received three Nano 50 Awards from the Foresight Instittute for his innovative bionano technology in 2006 and 2007, and was cit
Dark matter, although invisible, makes up most of the universe’s mass and creates its underlying structure. Dark matter’s gravity drives normal matter (gas and dust) to collect and build up into stars and galaxies. Although astronomers cannot see dark matter, they can detect its influence by observi
Shown in the artist’s rendering is the Mars Helicopter, a small, autonomous rotorcraft, will travel with NASA’s Mars Perseverance rover, currently scheduled to launch in July 2020, to demonstrate the viability and potential of heavier-than-air vehicles on the Red Planet. Destined to beco
