Neural networks predict planet mass

Whether they become bodies like Earth or Jupiter depends on different factors like the properties of the solids, the pressure and temperature in the disk and the already accumulated material. With computer models the astrophysicists try to simulate the growth…

Powering devices — with a desk lamp?

Batteries power most of our devices, and even some cars. But researchers now report in ACS Applied Materials & Interfaces a step toward running electronic devices in homes and offices on the light coming from lamps scattered around the room. The team developed special light harvesters, like those used for solar power, optimized to produce energy from ambient indoor lighting. Electronic gadgets increasingly are becoming…

NASA infrared imagery reveals powerful Tropical Cyclone Idai at Mozambique’s coast

IMAGE: At 4 a.m. EDT (0800 UTC) on Oct. 3, 2018 the MODIS instrument that flies aboard NASA's Terra satellite gathered infrared data on Tropical Cyclone Idai. Strongest thunderstorms circled the... view more  Credit: NASA/NRL NASA's Terra satellite captured an infrared image of Tropical Cyclone Idai approaching the coast of Mozambique. The infrared data provided cloud top temperatures that indicated powerful thunderstorms circled Idai's center. At…

Martian meteorites land at Army lab

ABERDEEN PROVING GROUND, Md. (March 13, 2019) -- NASA officials say that some rare and distinct meteorites found on Earth were actually blasted off Mars by a large impact event. One such rock from the red planet made its way to an Army laboratory recently for a special X-ray look inside. Researchers from the U.S. Army Combat Capabilities Development Command's Army Research Laboratory -- the…

NASA Invites Media to 17th SpaceX Cargo Launch to Space Station

Media accreditation now is open for the next SpaceX delivery of supplies, equipment and science investigations to the International Space Station.

Quasar jets confuse orbital telescope

Astrophysicists from the Moscow Institute of Physics and Technology, the Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), and NASA have found an error in the coordinates of active galactic nuclei measured by the Gaia space telescope, and helped correct it. The findings, published in The Astrophysical Journal, also serve as an independent confirmation of the astrophysical model of these objects. "One…

Scientists go to extremes to reveal make-up of Earth’s core

Experiments conducted at extreme conditions are giving scientists new insights into the chemical make-up of the Earth's core. Advanced laboratory techniques reveal that our planet's metal centre - more than 1,800 miles below the surface - also contains silicon, an element commonly found in stony meteorites. The findings support an existing theory that suggests Earth's formation around 4.5 billion years ago was driven by extensive…

NASA Astronauts Hague, Koch Arrive Safely at Space Station

Three crew members have arrived safely at the International Space Station, following a successful launch and docking of their Soyuz MS-12 spacecraft Thursday.

Physicists reverse time using quantum computer

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study comes out March 13 in Scientific Reports. "This is…

Astronomers discover 83 supermassive black holes in the early universe

A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the early Universe. This increases the number of black holes known at that epoch considerably, and reveals, for the first time, how common SMBHs were early in the Universe's history. Supermassive black holes are found at the centers of galaxies, and have masses millions or even billions of times that…
