Astronauts To Patch Up NASA’s NICER Telescope

Astronauts To Patch Up NASA’s NICER Telescope

6 min read NASA’s Near Space Network Enables PACE Climate Mission to ‘Phone Home’ The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA’s Near Space Network, which introduced two key enhancements for PACE and other … Read more

A Solar Neighborhood Census, Thanks to NASA Citizen Science

A Solar Neighborhood Census, Thanks to NASA Citizen Science

A small team of citizen scientists developed a tool called WISE View, using images from NASA’s WISE (Wide-Field Infrared Survey Explorer) mission, to easily stitch together images into animations. A larger group of volunteers then used those animations to find moving objects. “They’ve made the project more efficient for everyone else,” Kirkpatrick said. (WISE’s mission … Read more

Hubble Spots a Galaxy Hidden in a Dark Cloud

Hubble Spots a Galaxy Hidden in a Dark Cloud

However, we can’t fully appreciate the features of this galaxy — at least in visible light — because it’s partially concealed by a stretch of dark dust (lower-right third of the image). This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of … Read more

NASA’s TESS Temporarily Pauses Science Observations

NASA’s TESS Temporarily Pauses Science Observations

The TESS mission is a NASA Astrophysics Explorer operated by MIT in Cambridge, Massachusetts. Launched in 2018, TESS has been scanning almost the entire sky looking for planets beyond our solar system, known as exoplanets. The TESS mission has also uncovered other cosmic phenomena, including star-shredding black holes and stellar oscillations. Read more about TESS discoveries at nasa.gov/tess. Source … Read more

Hubble Peers at Pair of Closely Interacting Galaxies

Hubble Peers at Pair of Closely Interacting Galaxies

This image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image). Both galaxies lie approximately 160 million light-years from Earth, and their … Read more

NASA’s Webb Probes an Extreme Starburst Galaxy

NASA’s Webb Probes an Extreme Starburst Galaxy

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon … Read more

That Starry Night Sky? It’s Full of Eclipses

That Starry Night Sky? It’s Full of Eclipses

And astronomers can, in a sense, “see” eclipses among other systems of planets orbiting their parent stars. In this case, the eclipse is a tiny drop in starlight as a planet, from our point of view, crosses the face of its star. That crossing, called a transit, can register on sensitive light sensors attached to … Read more

Hubble Finds a Field of Stars

Hubble Finds a Field of Stars

The reason that Hubble can observe objects of such wildly different sizes is two-fold. First, the distance to an object will determine how big it appears from Earth, so entire galaxies that are relatively far away might take up the same amount of space in the sky as a globular cluster like NGC 1651 that … Read more

Three-Year Study of Young Stars with NASA’s Hubble Enters New Chapter

Three-Year Study of Young Stars with NASA’s Hubble Enters New Chapter

The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one … Read more
