ESA’s Earth Cloud Aerosol and Radiation Explorer (EarthCARE) mission is designed to advance our understanding of the role that clouds and aerosols play in reflecting incident solar radiation back out to space and trapping infrared radiation emitted from Earth’s surface.
The physics surrounding black holes is just plain weird. A gravitational well so strong that not even light can escape can do some pretty strange things to normal matter. Over the decades, plenty of theories have been put forward about what those strange things might be. And now, a new paper from physicists at the University of Oxford has proved that, once again, Einstein’s theory of gravity was right.
A future space observatory could use exo-eclipses to tease out exomoon populations.
Sending tourists to space is still relatively novel in the grand scheme of humanity’s journey to the stars. Dennis Tito took the first-ever paid trip in 2001, but since then, plenty of others have journeyed to the heavens. Increasingly, they’ve done so via systems developed by private companies. On Sunday, May 19th, Blue Origin, originally founded by Jeff Bezos to pursue his dreams of humanity’s future in space, successfully launched its seventh crewed mission – this time containing six first-time astronauts, including one that waited a long time for his day in space.
On May 10th, 2024, people across North America were treated to a rare celestial event: an aurora visible from the Eastern Seabord to the Southern United States. This particular sighting of the Northern Lights (aka. Aurora Borealis) coincided with the most extreme geomagnetic storm since 2003 and the 27th strongest solar flare ever recorded. This led to the dazzling display that was visible to residents all across North America but was also detected by some of Ocean Networks Canada‘s (ONC) undersea sensors at depths of almost three kilometers.

Ed Dwight, a 90-year-old artist and former Air Force test pilot who was denied a chance to become the first African American astronaut six decades ago, finally rocketed into space Sunday, fulfilling a cherished dream in a brief up-and-down flight out of the lower atmosphere.

ESA's fireball camera in Cáceres, Spain, captured this stunning meteor during the night of 18—19 May 2024 (00:46 CEST 19 May / 22:46 UTC 18 May).
New research may have revived the mystery of 8 Ursae Minoris b, a seemingly doomed exoplanet that shouldn’t exist.
Blue Origin sent six people to the final frontier today (May 19) on the company's first crewed spaceflight since August 2022.

A Quiet Place is expanding its universe with an ambitious prequel.
On the evening of Saturday (May 18) a bright fireball lit up the skies over Portugal and Spain in stunning green and blue as it streaked through Earth's atmosphere.
Leftover light from the young universe has a major flaw, and we don't know how to fix it. It's the cold spot. It's just way too big and way too cold.
NASA is studying innovative rocket system developed by Howe Industries that could reducing travel time to the Red Planet to just a few months.
The gravitational wave background was first detected in 2016. It was announced following the release of the first data set from the European Pulsar Timing Array. A second set of data has just been released and, joined by the Indian Pulsar Timing Array, both studies confirm the existence of the background. The latest theory seems to suggest that we’re seeing the combined signal of supermassive black hole mergers.
The giant outer planets haven’t always been in their current position. Uranus and Neptune for example are thought to have wandered through the outer Solar System to their current orbital position. On the way, they accumulated icy, comet-like objects. A new piece of research suggests as many as three kilomerer-sized objects crashed into them every hour increasing their mass. Not only would it increase the mass but it would enrich their atmospheres.
The hunt for extrasolar planets has revealed some truly interesting candidates, not the least of which are planets known as “Hot Jupiters.” This refers to a particular class of gas giants comparable in size to Jupiter but which orbit very closely to their suns. Strangely, there are some gas giants out there that have very low densities, raising questions about their formation and evolution. This is certainly true of the Kepler 51 system, which contains no less than three “super puff” planets similar in size to Jupiter but is about one hundred times less dense.
A pair of cubesats will measure far-infrared radiation from Earth's poles to improve climate predictions.
On Episode 111 of This Week In Space, Rod and Tariq talk with John Mulchaey, Director of the Carnegie Observatories, about the threat to completing two new giant astronomical observatories.
Earth may have gotten some of its water from 'dark comets,' and the forthcoming Vera C. Rubin Observatory could uncover key clues about these mysterious cosmic bodies.
Blue Origin is scheduled to launch a crewed mission for the first time in nearly two years on Sunday (May 19). Here's how to watch the action live.
