Iron-rich rocks near ancient lake sites on Mars could hold vital clues that show life once existed there, research suggests.
Last September, a massive new region of magnetic field erupted on the Sun's surface next to an existing sunspot. The powerful collision of magnetic fields produced a series of potent solar flares, causing turbulent space weather conditions at Earth. These were the first flares to be captured, in their moment-by-moment progression, by New Jersey Institute of Technology's (NJIT) recently expanded Owens Valley Solar Array (EOVSA).
From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists from Cracow have proposed their own explanation of this phenomenon and presented predictions related to it, about consequences that are particularly interesting for high-energy neutrino astronomy.
If humanity hopes to make it to Mars anytime soon, we need to understand not just technology, but the psychological dynamic of a small group of astronauts trapped in a confined space for months with no escape, according to a paper published in American Psychologist, the flagship journal of the American Psychological Association.
A team of astronomers has performed one of the highest resolution observations in astronomical history by observing two intense regions of radiation, 20 kilometers apart, around a star 6,500 light-years away. The observation is equivalent to using a telescope on Earth to see a flea on the surface of Pluto.
Based on new observational data, an international team led by astronomers at ETH Zurich identified at least six candidates for dark galaxies -- galaxies that have a few (if any) stars in them and are, for that reason, notoriously difficult to detect with current instruments.
The object is revolving around the sun in the vicinity of Jupiter but in the opposite direction from most other celestial bodies, according to a study featuring a Brazilian scientist as co-author. Through a computer simulation, the study shows that the orbit has been stable since the giant planets were formed.
A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system. The work is published in Monthly Notices of the Royal Astronomical Society: Letters.
After launching April 18, TESS has completed its lunar flyby to put it on track for its final science orbit, and has released a first test image.
Capitalizing on the unparalleled sharpness and spectral range of NASA's Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.
