Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary
Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world. “Since President Biden and Vice President Harris unveiled the first image from the James Webb Space Telescope two years…

Hubble Measures the Distance to a Supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to…

45 Years Ago: Skylab Reenters Earth’s Atmosphere
A few days before they left Skylab on Feb. 8, 1974, the final crew to occupy the station raised its altitude, hoping to keep it in orbit until a future space shuttle could revisit it. But higher than predicted solar activity caused the Earth’s atmosphere to expand, increasing drag on the large vehicle, causing its orbit to decay faster than…

Electrical and Mechanical Technician Clifton Brown
“We have a group photo of my first project here, ASTRO-H, and that one means a lot to me because I came [to that NASA project] fresh off the street. I was super scared and intimidated. It was me and three other [technicians], who were also all new, and a handful of very seasoned scientists and engineers. And we came…

Take a Summer Cosmic Road Trip With NASA’s Chandra and Webb
It’s time to take a cosmic road trip using light as the highway and visit four stunning destinations across space. The vehicles for this space get-away are NASA’s Chandra X-ray Observatory and James Webb Space Telescope. The first stop on this tour is the closest, Rho Ophiuchi, at a distance of about 390 light-years from Earth. Rho Ophiuchi is a…

Acting Center Chief Technologist Dr. Phillip Williams
“I did not know that NASA Langley was right here in my own backyard. I was born and raised in Portsmouth, Virginia, and NASA Langley is in Hampton, about 45 minutes away. All throughout elementary school, I didn’t know that NASA was here. I always thought NASA was in Florida or Texas or somewhere. “I was in this summer program…

Voyagers of Mars: The First CHAPEA Crew’s Yearlong Journey
When the first humans travel to the Red Planet, they will need to know how to repair and maintain equipment, grow their own food, and stay healthy, all while contending with Earth-to-Mars communication delays. They must also find ways to build comradery and have fun. The first all-volunteer CHAPEA (Crew Health and Performance Exploration Analog) crew accomplished all of that…

NASA’s Hubble Traces Dark Matter in Dwarf Galaxy Using Stellar Motions
The qualities and behavior of dark matter, the invisible “glue” of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it’s relevant to a galaxy’s evolution. While computer simulations suggest dark matter should pile up in…

Surfing NASA’s Internet of Animals: Satellites Study Ocean Wildlife
Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the newcomer. They zoom close and veer away at the last minute, as Gilmour slowly makes her way toward the…
