Chelyabinsk Meteorite

A newly published study uses the impact heat signatures in meteorites to date the Moon-forming impact between a large protoplanet and proto-Earth. The inner Solar System’s biggest known collision was the moon-forming giant impact between a large protoplanet and the proto-Earth. Kilometer-sized fragments from this impact hit main belt asteroids at much higher velocities than […]

Dark Matter Observed Interacting with Other Dark Matter

Using new Hubble Space Telescope imaging and VLT/MUSE integral field spectroscopy, astronomers reveal what may be the first signs of self-interacting dark matter. For the first time dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies made with ESO’s […]

Icy Tendrils Reaching into Saturn Ring Traced to Their Source

Using Cassini data and computer simulations, astronomers detail the source responsible for icy tendrils that reach into Saturn’s E ring. Long, sinuous, tendril-like structures seen in the vicinity of Saturn’s icy moon Enceladus originate directly from geysers erupting from its surface, according to scientists studying images from NASA’s Cassini spacecraft. This result is published online […]

Spitzer Finds a Planet Deep Within Our Galaxy

Using a method called microlensing, NASA’s Spitzer Space Telescope and OGLE’s Warsaw Telescope teamed up to reveal a remote gas planet that is located about 13,000 light-years away. The discovery demonstrates that Spitzer — from its unique perch in space — can be used to help solve the puzzle of how planets are distributed throughout […]

Investigating Magnetic Properties of Comet 67P

New data from Rosetta and Philae reveal that the nucleus of Comet 67P/Churyumov-Gerasimenko is not magnetized. Studying the properties of a comet can provide clues to the role that magnetic fields played in the formation of Solar System bodies almost 4.6 billion years ago. The infant Solar System was once nothing more than a swirling […]

Curiosity Weather Data Bolsters Case for Brine

New calculations indicate favorable conditions for small quantities of brine to form during some nights throughout the year on Mars. The possibility for liquid brines on Mars has wider implications for habitability and geological water-related processes. Martian weather and soil conditions that NASA’s Curiosity rover has measured, together with a type of salt found in […]

New Color Map Reveals Surface Diversity of Ceres

A new color map of Ceres reveals the differences in morphology and color across the surface of the dwarf planet, suggesting Ceres was once an active body. “This dwarf planet was not just an inert rock throughout its history. It was active, with processes that resulted in different materials in different regions. We are beginning […]

New Research Explains Saturn's Epic Tantrums

New research describes the effect responsible for the development of a huge storm that erupts about every 30 years on Saturn. The long-standing mystery of why Saturn seethes with enormous storms every 30 years may have been solved by scientists working with data from NASA’s Cassini mission. The tempests, which can grow into bright bands […]

Hubble Views Elliptical Galaxy NGC 2865

This Hubble image of the week shows elliptical galaxy NGC 2865, which is located roughly 100 million light-years from Earth. This NASA/ESA Hubble Space Telescope image shows an elliptical galaxy called NGC 2865. It lies just over 100 million light-years away from us in the constellation of Hydra — The Sea Serpent — and was […]

Eruptive Star Nova Vul 1670

A newly published study reveals that Nova Vul 1670 is not only rich in molecular species, its gas has dramatically unusual isotopic abundances (that is, the atoms present, carbon, oxygen and nitrogen in particular, have extra neutrons in their nuclei). Astronomers have known for decades that the merger of two normal stars is a frequent […]

Complex Cyanides Reveal Composition of a Protoplanetary Disk

Astronomers from the Harvard-Smithsonian Center for Astrophysics have detected the presence of complex organic molecules in a protoplanetary disk surrounding a young star, indicating that the conditions that spawned our Earth and Sun are not unique in the universe. This discovery, made with the Atacama Large Millimeter/submillimeter Array (ALMA), reveals that the protoplanetary disk surrounding […]

Solar Eruptions Can Have Profound Effects On Unprotected Planets

Using data from Venus Express, researchers show how the impact of a slow Interplanetary Coronal Mass Ejection (ICME) can have profound effects on planets without protective magnetospheres. While no one yet knows what’s needed to build a habitable planet, it’s clear that the interplay between the sun and Earth is crucial for making our planet […]
