Our Sun continues to demonstrate its awesome power in a breathtaking collection of recent images taken by the U.S. National Science Foundation’s (NSF’s) Daniel Inouye Solar Telescope, aka Inouye Solar Telescope, which is the world’s largest and most powerful ground-based solar telescope. These images, taken by one of Inouye’s first-generation instruments, the Visible-Broadband Imager (VBI), show our Sun in incredible, up-close detail.

Triggered Star Birth in the Nessie Nebula
Star formation is one of the oldest processes in the Universe. In the Milky Way and most other galaxies, it unfolds in cold, dark creches of gas and dust. Astronomers study sites of star formation to understand the process. Even though they know much about it, some aspects remain mysterious. That’s particularly true for the “Nessie Nebula” in the constellation Vulpecula. An international team led by astronomer James Jackson studies the nebula and its embedded star-birth regions. They found that it experienced a domino effect called “triggered star formation.”
Galaxy group blasts out record-breaking tail of hot gas after gobbling up neighbor (video)
A monstrous galactic cluster is devouring another group of galaxies whole, causing it to emit a 1.5 million light-year-long trail of hot gas from its rear — the largest of this type ever seen.
James Webb Space Telescope discovers 717 ancient galaxies that flooded the universe with 1st light
The James Webb Space Telescope has discovered hundreds of galaxies that existed when the universe was less than 600 million years old.

Long space missions take a toll on astronaut brains, study finds
Long spaceflights can cause astronauts' ventricles — cavities in the brain that hold cerebrospinal fluid — to enlarge by up to 25%. And it apparently takes years for the swelling to go down.

Phew, California’s Largest Reservoir is Nearly Full
California residents will be glad to know their reservoirs are nearly full again after years of drought. New satellite photos show the levels of Shasta Lake, California’s largest reservoir, going from 31% capacity last November to nearly 100% in May 2023. The reservoir was filled with heavy rains and a significant mountain snowpack that melted into the nearby rivers.
New tool 'cleans' ever-increasing satellite trails from Hubble photos
Scientists have developed a new tool that can keep Hubble Space Telescope photos free of the bright streaks caused by fast-moving satellites.

NASA’s Europa Clipper Taking “Message in a Bottle” to Jupiter
NASA believes in getting the public excited about space, and they’re carrying on this tradition by recently announcing that space fans from around the world can travel to Jupiter with the Europa Clipper mission. Though, not literally, but by adding their names to a microchip for the “Message in a Bottle” campaign that will also contain “In Praise of Mystery: A Poem for Europa”, which is an original poem by U.S. Poet Laureate Ada Limón.
Is it Time for a New Definition of “Habitable?”
Things tend to move from the simple to the complex when you’re trying to understand something new. This is the situation exoplanet scientists find themselves in when it comes to the term ‘habitable.’ When they were discovering the first tranche of exoplanets, the term was useful. It basically meant that the planet could have liquid water on its surface.
Missed the Mars Livestream? Here's the Video
When a mission to Mars reaches 20 years of service, that’s definitely reason to celebrate. ESA’s Mars Express celebrated by airing the first-ever livestream of images, sent directly from the Visual Monitoring Camera (VMC) on board the spacecraft. For an hour, it sent back images from the Red Planet in as close to real-time as the speed of light would allow.
