Black hole at center of Milky Way unpredictable and chaotic

London, UK (SPX) Jan 13, 2022
An international team of researchers, led by postgraduate student Alexis Andres, has found that the black hole at the centre of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term. The team analysed 15 years' worth of data to come to this conclusion. The research was initiated by Andres in 2019 when he was a summer student at the University of Amster

Oxygen ions in Jupiter's innermost radiation belts
Write a comment
Gottingen, Germany (SPX) Jan 13, 2022
Planets like Earth, Jupiter, and Saturn with global magnetic fields of their own are surrounded by so-called radiation belts: Trapped in the magnetic field, fast moving charged particles such as electrons, protons, and heavier ions whiz around thus forming the invisible, torus-shaped radiation belts. With their high velocities reaching almost the speed of light, the particles can ionize other mo

Sol 3354: Tantalizingly Out of Reach

Pasadena CA (JPL) Jan 13, 2022
Today Curiosity is doing a little bit of everything: some contact science, some targeted science, and a little driving. When we started planning this morning, we had a beautiful view of the small ledge in front of us, named "The Prow," which shows some amazing layering. We also can see some disturbances in the sand that may be sliding caused by our approach.

Widespread megaripple activity on Martian North Pole
Write a comment
Tucson AZ (SPX) Jan 13, 2022
Megaripples, intermediate-scale bedforms caused by the action of the wind, have been studied extensively and thought to be largely inactive relics of past climates, save for a few exceptions. A new paper by Planetary Science Institute Research Scientist Matthew Chojnacki shows that abundant megaripple populations were identified across the north polar region of Mars and were found to be migratin

New Delhi (Sputnik) Jan 13, 2022
India's flagship human spaceflight mission, Gaganyaan, has completed the design and testing phases. The Indian Space Research Organisation (ISRO) plans to launch two uncrewed missions ahead of the final mission in 2023.
India's space exploration agency ISRO achieved a significant milestone with the successful long-duration cryogenic engine test for the Gaganyaan project on Wednesday.

Pandora mission to study stars and exoplanets continues toward flight
Write a comment
The Pandora mission, co-led by a national laboratory and a NASA flight center, has passed a crucial step on its path to study stars and planets outside our solar system, or exoplanets.
After a successful concept study report and system requirements review, NASA approved the mission to continue toward flight.

Machine learning algorithms help scientists explore Mars
Write a comment
NASA's Curiosity rover has been exploring the Red Planet's surface for nearly a decade, with its main mission being to determine whether Mars was once habitable. While the rover's investigations have indeed confirmed that Mars was once a watery world filled with potentially life-sustaining chemistry, there's still much to learn. Curiosity's mountains of data offer an opportunity to use machine learning algorithms to investigate the planet's surface in even more detail.
A new article in Earth and Space Science focuses on the data collected by Curiosity's Chemistry and Camera (ChemCam) instrument package. ChemCam combines two instruments: a laser-induced breakdown spectrometer (LIBS) and a remote micro-imager (RMI) for high-resolution imaging.

Mini monster black hole could hold clues to giant's growth
Write a comment
Huntsville AL (SPX) Jan 11, 2022
The discovery of a supermassive black hole in a relatively small galaxy could help astronomers unravel the mystery surrounding how the very biggest black holes grow.
Researchers used NASA's Chandra X-ray Observatory to identify a black hole containing about 200,000 times the mass of the Sun buried in gas and dust in the galaxy Mrk 462.
Mrk 462 contains only several hundred million

Astronomers identify potential clue to reinonization of universe
Write a comment
Iowa City IA (SPX) Jan 11, 2022
About 400,000 years after the universe was created began a period called "The Epoch of Reionization." During this time, the once hotter universe began to cool and matter clumped together, forming the first stars and galaxies. As these stars and galaxies emerged, their energy heated the surrounding environment, reionizing some of the remaining hydrogen in the universe.

Ocean Physics Explain Cyclones on Jupiter

San Diego CA (SPX) Jan 11, 2022
Hurtling around Jupiter and its 79 moons is the Juno spacecraft, a NASA-funded satellite that sends images from the largest planet in our solar system back to researchers on Earth. These photographs have given oceanographers the raw materials for a new study published in Nature Physics that describes the rich turbulence at Jupiter's poles and the physical forces that drive the large cyclones.
