There is no weather in space - but there is weathering: Celestial bodies are bombarded by high energy particles. On the Mars moon Phobos, the situation is complicated: It is hit by particles from the sun, but it is partly shielded by Mars. New experiments explain what is going on, in 2024 a space mission will reach Phobos and check the results.
The missing dark matter in certain galaxies can be explained by the effects of tidal disruption: the gravity forces of a neighboring massive galaxy, literally tearing the smaller galaxy apart.
Wisps of pulsating aurora lights are a rare, yet magical sight. Now, scientists suggest they could be associated with destruction of part of the ozone.
Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. But don't worry, this doesn't mean that our planet is critical. Instead the changes are results of a better model of the Milky Way Galaxy based on new observation data, including a catalog of objects observed over the course of more than 15 years by the Japanese radio astronomy project VERA.
Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe. The WINERED instrument allows for better observations of astronomical bodies like quasars in the early universe, billions of years ago. Researchers hope this deeper level of exploration could help answer questions about the origins not only of metals in the universe but also of the stars themselves.
A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400 light years away, a discovery that provides an opportunity to study how our own solar system developed.
Using NASA's SOFIA telescope, University of Kansas researchers have found CQ 4479, a galaxy which never had been closely studied before, to be generating new stars in spite of a luminous AGN at the galaxy's center.
New data from the NASA/ESA Hubble Space Telescope provides further evidence for tidal disruption in the galaxy NGC 1052-DF4. This result explains a previous finding that this galaxy is missing most of its dark matter. By studying the galaxy's light and globular cluster distribution, astronomers have concluded that the gravity forces of the neighbouring galaxy NGC 1035 stripped the dark matter from NGC 1052-DF4 and are now tearing the galaxy apart.
The Borexino experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified. The findings are the result of years of efforts devoted to bringing the background sources in the energy range of the CNO neutrinos under control.
Giant planets that developed early in a star system's life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new study by University of Warwick astronomers.
