Star Trek debuted 54 years ago on Sept. 8, 1966. Fans of the television science fiction series Star Trek were saddened when the show’s final episode aired on June 3, 1969. It seemed like the end of a very short era, as the program had only been on the air for three seasons. But, the show and its influence continue. In the documentary “NASA on the Edge of For...
The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images. Roman will peer through dust and across vast stretches of space and time to study the universe u...
The first solid rocket booster test for Space Launch System (SLS) missions beyond Artemis III is seen here during a two-minute hot fire test, Wednesday, September 2, 2020, at the T-97 Northrop Grumman test facility in Promontory, Utah. The flight support booster is structurally identical to each of the five-segment solid rocket boosters on the SLS rocket and...
NASA’s Mars Pathfinder mission landed on the Red Planet on July 4, 1997. It’s tiny rover, named Sojourner after abolitionist Sojourner Truth, spent 83 days of a planned seven-day mission exploring the Martian terrain, acquiring images, and taking chemical, atmospheric and other measurements. When the Mars Pathfinder spacecraft approached its dest...

While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2,400 light-years away. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (the Swan), where it covers an are...
In this large celestial mosaic taken by NASA’s Spitzer Space Telescope and published in 2019, there’s a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. Some of these clusters are older than others and more evolved, making this a generational stellar portrait. This image is of the Cepheus C and Cep...
What does this Fermi Gamma-ray Space Telescope Spirograph have in common with Women’s Equality Day? The Fermi mission is run by Project Scientist Dr. Elizabeth Hays, one of many female scientists and leaders at NASA. Hays and her deputy, Dr. Judith Racusin, are astrophysicists in the Astrophysics Science Division of NASA’s Goddard Space Flight Center i...
Discovered in 2016, a roughly Earth-sized planet orbiting our nearest neighboring star might be habitable, according to astronomers using the European Southern Observatory’s 3.6-meter telescope at La Silla, Chile, along with other telescopes around the world. The exoplanet is at a distance from its star that allows temperatures mild enough for liquid w...
