(Swedish Research Council) Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using measurements from the Swedish particle instrument ASPERA-3 on the Mars Express spacecraft. Show More Summary
(University of Hawaii at Manoa) A team of astronomers from Maryland, Hawaii, Israel and France has produced the most detailed map ever of the orbits of galaxies in our extended local neighborhood, showing the past motions of almost 1,400 galaxies within 100 million light years of the Milky Way.

(Mary Ann Liebert, Inc./Genetic Engineering News) The US space exploration program should continue to focus on robotic sample recovery and human missions to Mars, says Scott Hubbard, Editor-in-Chief of New Space.
(National Science Foundation) Observations of two galaxies made with the National Science Foundation-funded Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope suggest that large galaxies formed faster than scientists had previously thought.
(Cornell University) Rachel Bean, professor of astronomy and senior associate dean of undergraduate education for the College of Arts and Sciences at Cornell University, is among a team of 27 scientists who won a share of the $3 million 2018 Breakthrough Prize in fundamental physics this week.
(University of Florida) In a paper to be published this week in the journal Science, University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought. Show More Summary
(American Association for the Advancement of Science) A sudden flare and cooling of gas around a black hole in a binary system has offered astronomers a rare opportunity to measure the system's magnetic field, finding it weaker than expected.
(The Mount Sinai Hospital / Mount Sinai School of Medicine) Research could lead to new treatment for solar retinopathy.
(Association of Universities for Research in Astronomy (AURA)) Observations reveal the mass of earliest known supermassive black hole which radiates from an era in the universe only 690 million years after the Big Bang. Researchers,Show More Summary
(National Radio Astronomy Observatory) ALMA observations push back the epoch of massive-galaxy formation even further by identifying two giant galaxies seen when the universe was only 780 million years old, or about 5 percent its current age.
(Massachusetts Institute of Technology) A team of astronomers has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar and presents a puzzle as to how such a huge object could have grown so quickly.
(Carnegie Institution for Science) A team of astronomers led by Carnegie's Eduardo Bañados used Carnegie's Magellan telescopes to discover the most-distant supermassive black hole ever observed. It resides in a luminous quasar and its light reaches us from when the universe was only 5 percent of its current age -- just 690 million years after the Big Bang.
(Association of Universities for Research in Astronomy (AURA)) To understand when supermassive black holes first appeared, astronomers scan the skies for actively-feeding black holes (known as 'quasars') from the Universe's distant past. Show More Summary
(Brown University) New research suggests that the bulk of clay minerals on Mars could have been formed as the planet's crust cooled and solidified, not by later interactions with water on the surface as has long been assumed.
(Simons Foundation) A newfound pair of galaxies from the early universe is so massive that it nearly breaks the current understanding of how the cosmos evolved. The larger of the pair is the heftiest galaxy ever seen from the first billion years of the universe. Show More Summary
(University of Southern Denmark) A whole lot of zig-zagging: Perhaps that is what happens when the universe's mysterious dark matter particles hit the Earth. SDU researchers can now show through simulations how it might look.
(NASA/Goddard Space Flight Center) When comet 45P zipped past Earth early in 2017, researchers observing from NASA's Infrared Telescope Facility, or IRTF, in Hawai'i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial details about ices in Jupiter-family comets and reveal that quirky 45P doesn't quite match any comet studied so far.
(NASA/Goddard Space Flight Center) A NASA-led team has found evidence that the oversized planet WASP-18b is wrapped in a smothering stratosphere loaded with carbon monoxide and devoid of water. The findings come from a new analysis of observations made by the Hubble and Spitzer space telescopes.
(W. M. Keck Observatory) Scientists are investigating the nature of planetary-mass bodies that orbit stars, finding new clues to their origins.
(University of California - Berkeley) The nature of dark matter remains elusive, with numerous experimental searches for WIMPs coming up empty-handed and MACHOs all but abandoned. Theorists have proposed a different type of dark matter...Show More Summary
