NASA's Juno captures detailed images of Europa's surface
Thursday, 16 May 2024 14:27
NASA's Juno spacecraft has provided high-definition images of Jupiter's moon Europa, supporting the theory that the icy crust at the poles has shifted. A new image shows signs of potential plume activity and ice shell disruption.
The findings were published in the Planetary Science Journal and JGR Planets.
On September 29, 2022, Juno flew within 220 miles of Europa's surface, capturi Earth-sized planet discovered orbiting ultra-cool red dwarf star

An international team of astronomers has detected a new Earth-sized planet orbiting an ultra-cool red dwarf star, located 55 light years away.
The planet, named SPECULOOS-3 b, is the second of its kind discovered around this type of star. It completes an orbit of the star in about 17 hours. The star is more than twice as cold as our sun and significantly less massive and luminous.

Astronomers at MIT, the University of Liege, and elsewhere have discovered a new planet orbiting a small cold star, a mere 55 light years away. The nearby planet is similar to Earth in its size and rocky composition, though that's where the similarities end. Because this new world is likely missing an atmosphere.

As construction continues on the Vera Rubin Observatory, the skies above its mountaintop home grow more and more crowded following every rocket launch. Astronomers, conscious of the plans for mega-constellations of new satellites in the next few years, are rightfully worried: will these satellites and the tiny bits of debris that come with every deployment and collision affect the new telescope' Protected: The Satellite Industry Will Answer the Demand for Telco Interoperability with Next Generation Ground Infrastructure

Hera plus one: enter the CubeSat Canada’s wildfire season begins
Thursday, 16 May 2024 11:15
Wildfire season has arrived in full force in Canada, prompting evacuation orders and alerts in several towns in British Columbia and Alberta due to the danger of uncontrolled blazes.
Hazardous smoke from the fires has also triggered air quality alerts in Canada and the northern US. Satellite technology, including the Copernicus Sentinel-5P satellite and ESA’s Fire Atlas, plays a crucial role in monitoring these wildfires.

NASA researchers bid farewell to 'flying laboratory' at Ames Research Center
Thursday, 16 May 2024 10:23
For many NASA scientists, flying aboard a decked-out Douglas DC-8 plane provided them some unique glimpses of Earth: the Moai on Easter Island, Central Park in New York and Mount Vesuvius in Italy.
On May 15, some of the same scientists who worked on that "flying laboratory" looked on as it made one last flight over Ames Research Center in Mountain View before its retirement.
Reem Hannun, a research scientist in the atmospheric science branch, attended the flyover with her two children before taking them to school. As the twins played around the trees and commented on the big plane that flew close to the ground for them to see, she recalled how she got her start at NASA doing science and reading field measurements on the plane.
"It's just cool to see all these different measurements for atmospheric composition, and it's a great community to be a part of, and you get to travel the world doing science," Hannun said.
The plane, owned by NASA, was one of seven DC-8 planes still in operation internationally. Thomas Matthews, lead operations engineer for the aircraft and main mission director, said that NASA used the plane for 37 years, but the aging aircraft needed to be replaced as it was getting harder to sustain.
Webb detects most distant black hole merger to date
Thursday, 16 May 2024 07:00
An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the Universe was only 740 million years old. This marks the most distant detection of a black hole merger ever obtained and the first time that this phenomenon has been detected so early in the Universe.
