NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day with the agency’s #GlobalSelfie event. While NASA satellites constantly look at Earth from space, on Earth Day we’re asking you to step outside and take a picture of yourself in your corner of the world. Then post it to social media using the hashtag #GlobalSelfie. Bonus points if your #GlobalSelfie features your favorite body of water! About 71% of our Blue Marble is covered by water, and that water is one of the main reasons why Earth is like no other planet we’ve found in this solar sy ..read more

Rosario  This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than g ..read more

4 min read AI for Earth: How NASA’s Artificial Intelligence and Open Science Efforts Combat Climate Change Lights brighten the night sky in this image of Europe, including Poland, taken from the International Space Station. NASA As extreme weather events increase around the world due to climate change, the need for further research into our warming planet has increased as well. For NASA, climate research involves not only conducting studies of these events, but also empowering outside researchers to do the same. The artificial intelligence (AI) efforts spearheaded by the agency offer a powe ..read more

NASA/JPL-Caltech/LANL Earth planning date: Wednesday, April 17, 2024 Curiosity continues to make progress along the margin of upper Gediz Vallis ridge, investigating the broken bedrock in our workspace and acquiring images of the ridge deposit as the rover drives south. Today’s 2-sol plan focused on a DRT, contact science, and drive on the first sol, followed by untargeted remote sensing on the second sol. &nb ..read more

This animation is an artist’s concept of Loki Patera, a lava lake on Jupiter’s moon Io, made using data from the JunoCam imager aboard NASA’s Juno spacecraft. With multiple islands in its interior, Loki is a depression filled with magma and rimmed with molten lava. Credit: NASA/JPL-Caltech/SwRI/MSSS Imagery from the solar-powered spacecraft provides close-ups of intriguing features on the hellish Jovian moon. Scientists on NASA’s Juno mission to Jupiter have transformed data collected during two recent flybys of Io into animations that highlight two of the Jovian moon’s most dramatic features ..read more

The rapid pace of preparations for the first Moon landing continued in April 1969. The successful Apollo 9 mission in March cleared the way for Apollo 10 to test all three components of the spacecraft in lunar orbit in May, in a dress rehearsal for the landing itself. Apollo 10 astronauts Thomas P. Stafford, John W. Young, and Eugene A. Cernan and their backups L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell continued training in spacecraft simulators while engineers prepared their Saturn V rocket and Apollo spacecraft for the mid-May launch. Preparations continued in parallel for Apol ..read more

The first rocket launched at 2:13 p.m. local Alaska time for the Focusing Optics X-ray Solar Imager (FOXSI) mission that used X-ray vision to observe the Sun during the solar flare event by focusing directly on high-energy X-rays. The second rocket launched at 2:14 p.m. for the High Resolution Coronal Imager, or Hi-C, missi ..read more

5 min read Hubble Goes Hunting for Small Main Belt Asteroids Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don’t stop to be photographed as they zip along their orbits around the Sun. Astronomers recently used a trove of archived images taken by NASA’s Hubble Space Telescope to visually snag a largely unseen population of smaller asteroids in their tracks. The treasure hunt required perusing 37,000 Hubble images spanning 19 years. The payoff was finding 1,701 aste ..read more
