Princeton geoscientists Blair Schoene and Gerta Keller led an international team of researchers who have assembled the first high-resolution timeline for the massive eruptions in India's Deccan Traps, determining that the largest eruption pulse occurred less than 100,000 years before the mass extinction that killed the (non-avian) dinosaurs.
After several years of analysis, a team of planetary scientists using NASA's Hubble Space Telescope has at last come up with an explanation for a mysterious moon around Neptune that they discovered with Hubble in 2013.
When a stream of charged particles known as the solar wind careens onto the moon's surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich the moon's surface in ingredients that could make water, NASA scientists have found.
An international study led by researchers from the Institute of Space Sciences, from the Spanish National Research Council (CSIC) and the Institut d'Estudis Espacials de Catalunya has discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets.
The Zwicky Transient Facility (ZTF), an automated sky survey project based at Caltech's Palomar Observatory near San Diego, California, has produced its first bounty of new results. Since officially beginning operations in March 2018, the new instrument has discovered 50 small near-Earth asteroids and more than 1,100 supernovae, while observing more than 1 billion stars in the Milky Way galaxy.
The Zwicky Transient Facility, based at the Palomar Observatory, has identified over a thousand new objects and phenomena in the night sky, including more than 1,100 new supernovae and 50 near-Earth asteroids. University of Washington scientists are part of the ZTF team and led the development of the collaboration's alert system, which informs science teams of possible new objects or changes to known objects in the sky.
A team of Japanese and American scientists has visualized meteorite components at resolution powers much higher than ever before. Their efforts resulted in a much better look at -- and enhanced understanding of -- substances inside carbonaceous chondrites, the organic-containing meteorites that land on Earth. These substances include hydrogen, carbon, nitrogen and water, all of which are needed for life.
Astronomers at the University of California, Riverside, have teamed with teachers at the California School for the Deaf, Riverside, or CSDR, to design an astronomy workshop for students with hearing loss that can be easily used in classrooms, museums, fairs, and other public events. The workshop utilized a sound stage that allowed the CSDR students to 'feel' vibrations from rockets, stars, galaxies, supernovae, and even remnants of the Big Bang itself.
Astronomers using ALMA have detected various complex organic molecules around the young star V883 Ori. A sudden outburst from this star is releasing molecules from the icy compounds in the planet forming disk. The chemical composition of the disk is similar to that of comets in the modern solar system. Sensitive ALMA observations enable astronomers to reconstruct the evolution of organic molecules from the birth of the solar system to the objects we see today.
A new compound based on iridium, a rare metal which landed in the Gulf of Mexico 66 million years ago, hooked onto albumin, a protein in blood, can attack the nucleus of cancerous cells when switched on by light, University of Warwick researchers have found.
