The Universe’s Brightest Lights Have Some Dark Origins

Did you know some of the brightest sources of light in the sky come from the regions around black holes in the centers of galaxies? It sounds a little contradictory, but it’s true! They may not look bright to our eyes, but satellites have spotted oodles of them across the universe.  One of those satellites […]

NASA, International Astronauts to Connect with Students in Texas

NASA astronaut Nichole Ayers and JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi will answer prerecorded questions about science, technology, engineering, and mathematics from students in Mansfield, Texas, while aboard the International Space Station. The 20-minute space-to-Earth call will take place at 10:40 a.m.

¿Qué es una caminata espacial? (Grados 5.o a 8.o)

Este artículo es para estudiantes de 5.o a 8.o grado. Cada vez que un astronauta sale de un vehículo espacial, se dice que hace una actividad extravehicular (EVA, por sus siglas en inglés). A esto también se le llama caminata espacial. El astronauta ruso Alexei Leonov hizo la primera caminata espacial el 18 de marzo de 1965. […]

Sols 4522-4524: Up on the Roof

Written by Deborah Padgett, OPGS Task Lead at NASA’s Jet Propulsion Laboratory Earth planning date: Friday, April 25, 2025 On Sols 4520 and 4521, Curiosity was supposed to study layered rocks in its workspace, then drive on. Unfortunately, a communications pass didn’t go as expected, preventing this plan from being transmitted.

How to Contribute to Citizen Science with NASA

A cell phone, a computer—and your curiosity—is all you need to become a NASA citizen scientist and contribute to projects about Earth, the solar system, and beyond. Science is built from small grains of sand, and you can contribute yours from any corner of the world. All you need is a cell phone or a […]

NASA Advances Precision Landing Technology with Field Test at Kennedy

Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain. NASA’s official lunar landing requirement is to […]

Hubble Spots a Squid in the Whale

Today’s rather aquatic-themed NASA/ESA Hubble Space Telescope image features the spiral galaxy Messier 77, also known as the Squid Galaxy, which sits 45 million light-years away in the constellation Cetus (The Whale). The designation Messier 77 comes from the galaxy’s place in the famous catalog compiled by the French astronomer Charles Messier.
