New aurorae detected on Jupiter's four largest moons
Friday, 17 February 2023 05:55
Astronomers using W. M. Keck Observatory on Maunakea in Hawai?i have discovered that aurorae at visible wavelengths appear on all 4 major moons of Jupiter: Io, Europa, Ganymede, and Callisto. Using Keck Observatory's High-Resolution Echelle Spectrometer (HIRES) as well as high-resolution spectrographs at the Large Binocular Telescope and Apache Point Observatory, a team led by Caltech and Boston Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?

The James Webb Space Telescope - the most precise telescope ever built - was decisive in discovering the frozen forms of a long series of molecules, such as carbon dioxide, ammonia, methane, methanol and even more complex molecules, frozen out as ices on the surface of small dust grains.
The dust grains grow in size when being a part of the discs of gas and dust forming around young stars. Webb reveals intricate networks of gas, dust in nearby galaxies

Peering through obscuring clouds of dust, the MIRI instrument has revealed networks of giant cavities and blown-out bubbles in the gaseous arms of distant galaxies. Researchers using NASA's James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths.

What is a UFO? The US shot down three mysterious objects as interest and concern increase over unidentified craft
Thursday, 16 February 2023 18:20
On the heels of the Feb. 4, 2023, shooting down of a Chinese balloon suspected of spying on the U.S., American fighter jets have shot down three additional objects in or near U.S. airspace.
When the media asked Glen VanHerck, the Air Force general responsible for overseeing North American airspace, about these events, he refused to rule out extraterrestrial forces at play. Other military officialslater clarified that otherworldly origins aren't a serious consideration, but the comment highlighted the U.S. government's lack of knowledge about these objects.
As a space policy expert, I'm often confronted with questions about UFOs and little green people. However, as these recent episodes have shown, a UFO is far more likely to be human-made, rather than originating from some faraway place in the universe.
An extremely lightweight fission rocket could reach the solar gravitational lens in 15 years
Thursday, 16 February 2023 18:04
Novel propulsion ideas for moving around space seem like they're a dime a dozen recently. Besides the typical argument between solar sails and chemical propulsion lies a potential third way—a nuclear rocket engine. While we've discussed them here at UT before, NASA's Institute of Advanced Concepts has provided a grant to a company called Positron Dynamics for the development of a novel type of nuclear fission fragment rocket engine (FFRE). It could strike the balance between the horsepower of chemical engines and the longevity of solar sails.
FFREs are not a new concept in themselves, but many have massive technical hurdles to overcome before they can be considered useful. Their advantages, such as high specific impulse and extremely high power density, are offset by their disadvantages, such as requiring a complicated form of plasma levitation.

Researchers using the NASA/ESA/CSA James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths. The data have enabled an initial collection of 21 research papers which provide new insight into how some of the smallest-scale processes in the Universe — the beginnings of star formation — impact the evolution of the largest objects in our cosmos: galaxies.
