“The circumgalactic medium plays a huge role in that cycling of that gas. So, being able to understand what the CGM looks like around galaxies of different types — ones that are star-forming, those that are no longer star-forming, and those that are transitioning between the two — we can observe [how] changes in this reservoir may actually be driving the changes in the galaxy itself.”

As technology evolves astronomers will likely be able to look at the CGM of other more distant galaxies and learn more about them as well.

The colliding of galaxies sounds terrifying.

NASA’s Juno spacecraft has just completed its 66th flyby of Jupiter, and the latest batch of images it has sent back to Earth are truly spectacular.

The spacecraft was launched back in 2011, reaching Jupiter five years later in 2016 after journeying for 1.7 billion miles. Ever since then, the probe has been zipping past Jupiter and its moons, capturing images and sending back data bursting with exquisite details.

“Jupiter is the Rosetta Stone of our solar system. Juno is going there as our emissary—to interpret what Jupiter has to say,” Scott Bolton, Juno’s principal investigator, said in a statement on NASA’s website.

The laser violated a law of the universe by travelling faster than light. A relative theory by Einstein was not believing that this could be possible.

An astronaut captured an enthralling image of Onekotan Island from the International Space Station, showcasing the Krenitsyna Volcano of the Kuril Islands chain.

This remarkable photo highlights geographical features like the Tsar-Rusyr caldera and its deep, reflective Kol’tsevoye Lake, which is among Russia’s deepest. The volcano’s last eruption in 1952 adds a historical layer to the viewing experience, juxtaposing the rugged terrain against the caldera’s lush, vegetated landscape.

Capturing onekotan: a stunning image from space.

Astronomers have observed Jupiter’s legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises — especially when NASA’s Hubble Space Telescope takes a close-up look at it.

Hubble’s new observations of the famous red storm, collected 90 days between December 2023 to March 2024, reveal that the GRS is not as stable as it might look. The recent data show the GRS jiggling like a bowl of gelatin. The combined Hubble images allowed astronomers to assemble a time-lapse movie of the squiggly behavior of the GRS.

“While we knew its motion varies slightly in its longitude, we didn’t expect to see the size oscillate. As far as we know, it’s not been identified before,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, lead author of the science paper published in The Planetary Science Journal. “This is really the first time we’ve had the proper imaging cadence of the GRS. With Hubble’s high resolution we can say that the GRS is definitively squeezing in and out at the same time as it moves faster and slower. That was very unexpected, and at present there are no hydrodynamic explanations.”
