When NASA launched TESS (Transiting Exoplanet Survey Satellite) in 2018, it had a specific goal. While its predecessor, the Kepler spacecraft, found thousands of exoplanets, many of them were massive gas giants. TESS was sent into space with a promise: to find smaller planets similar in size to Earth and Neptune, orbiting stable stars without … Continue reading “NASA Promised More Smaller, Earth-size Exoplanets
The most comprehensive and widely-held theory of how the Moon formed is called the ‘giant impact hypothesis.’ That hypothesis shows that about 150 million years after the Solar System formed, a roughly Mars-sized planet named Theia collided with Earth. Though the timeline is hotly-debated in the scientific community, we know that this collision melted Theia … Continue reading “The Moon is Older Than Scientists Thought” The post The Moon is Older Than Scientists Thought appeared first on Universe Today
As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith
A new video shows Japan’s Hayabusa 2 sample return spacecraft collecting samples from asteroid Ryugu. The spacecraft has been at Ryugu for months now, and it’s all been leading up to this. In the video, you can clearly see airborne asteroid dust and particles swirling around in the low gravity
Elon Musk has posted a four-panel video of the Falcon re-entry on his Twitter feed and it’s driving even jaded space-watchers into a frenzy.

The ESA’s Gaia mission recently allowed astronomers to catch a glimpse of Europa as it passed in front of a star, leading to new discoveries about this fascinating moon. The post Thanks to Gaia, we Now Know Exactly How Big Europa is appeared first on Universe Today .
After months of discussion, the space agencies behind the Lunar Gateway have decided how the space station will orbit the Moon. NASA and the ESA are developing the Lunar Gateway jointly, and the orbital path that it will follow around the Moon is a key part of mission design. It’ll affect all the vital aspects … Continue reading “The Lunar Gateway Will be in a “Near-Rectilinear Halo Orbit”” The post The Lunar Gateway Will be in a “Near-Rectilinear Halo Orbit” appeared first on Universe Today .
Some lakes on Titan have ring-like shapes around them, and scientists are trying to find out how they formed. Understanding how they formed may tell us something about how the entire region they’re in, including the lakes, formed
LightSail 2, the brainchild of The Planetary Society, has gifted us two new gorgeous images of Earth.
Dick Battin stood on his driveway in the New England frosty pre-dawn back in October 1957, straining his eyes to see Sputnik fly overhead.
Why report on an asteroid that has no chance of hitting Earth? Because this asteroid, known as 2006 QV89, has a history. A history of being kind of hard to track.
The idea of somehow terra-forming Mars to make it more habitable is a visionary, sci-fi dream.
