NASA Hubble Content-For Informational Purposes. This mosaic was assembled in 2018 from dozens of images taken by the Mast Camera (Mastcam) on NASA’s Curiosity rover. In the image, you’re looking uphill at Mount Sharp, which is in the middle of Gale Crater on Mars. The scene has been white-balanced so the colors of the rock… Continue reading 00-Gale Crater on Mars. Colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth.

Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be repaired and upgraded. Astronauts using custom-designed tools performed challenging spacewalks on five servicing missions from 1993 to 2009 to keep Hubble… Continue reading 172-Hubble Tool Time Episode 5: Servicing Mission 3B

M75 is the most centrally concentrated globular cluster in Messier’s catalog, with the majority of its stars located in a large nucleus. In total, there are about 400,000 stars in the globular cluster. M75 is believed to be around 13 billion years old and sits approximately 67,500 light-years away from Earth. This Hubble image of… Continue reading 179-Messier M75-This globular cluster holds roughly 400,000 stars.

Exomoons: Why are massive moons very important for life? With the discovery of thousands of exoplanets around other stars, scientists have begun to wonder about the moons which orbit them. In particular how these so called exomoons affect the habitability of the planets they orbit. It turns out that having a massive moon was important… Continue reading 180-Did the Hubble Telescope Confirm the First Exomoon?

Observatories including NASA’s Hubble Space Telescope found that the interstellar object named ‘Oumuamua gained an extra boost of speed, which likely comes from comet-like jets of gas. https://youtu.be/JG9x6tkf8mg

The Hubble Space Telescope has orbited Earth for more than 28 years, changing the way we look at the universe. Here at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, we’ll take you inside the Space Telescope Operations Control Center, where Hubble’s flight operations team communicates with the spacecraft and receives data and telemetry from… Continue reading 182-Visit Hubble Operations for its 28th Anniversary in 360°
