New survey hints at exotic origin for the Cold Spot

Tue, 25 Apr 2017 14:19:27 EDT

A supervoid is unlikely to explain a 'Cold Spot' in the cosmic microwave background, according to the results of a new survey, leaving room for exotic explanations like a collision between universes. The researchers, led by postgraduate student Ruari Mackenzie and Professor Tom Shanks in Durham University's Centre for Extragalactic Astronomy, publish their results in Monthly Notices of the Royal Astronomical Society.

Team discovers lull in Mars' giant impact history

Tue, 25 Apr 2017 11:14:16 EDT

From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution. Studying the early bombardment history of Mars, scientists at Southwest Research Institute (SwRI) and the University of Arizona have discovered a 400-million-year lull in large impacts early in Martian history.

Into the submillimeter—the early universe's formation

Tue, 25 Apr 2017 10:10:01 EDT

In order to make sense of our universe, astronomers have to work hard, and they have to push observing technology to the limit. Some of that hard work revolves around what are called sub-millimeter galaxies (SMGs.) SMGs are galaxies that can only be observed in the submillimeter range of the electromagnetic spectrum.

Astrophysicists study 'rejuvenating' pulsar in a neighboring galaxy

Tue, 25 Apr 2017 10:00:01 EDT

Lomonosov Moscow State University scientists published the results of a study of unique ultra-slow pulsar XB091D. This neutron star is believed to have captured a companion only a million years ago, and since then, has been slowly restoring its rapid rotation. The young pulsar is located in one of the oldest globular star clusters in the Andromeda galaxy, where the cluster may once have been a dwarf galaxy.

Astronaut Peggy Whitson broke the U.S. record Monday for most time in space and talked up Mars during a congratulatory call from President Donald Trump.

Cassini, Voyager missions suggest new picture of Sun's interaction with galaxy

Mon, 24 Apr 2017 11:23:13 EDT

New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic field from the sun—calling into question the alternate view of the solar magnetic fields trailing behind the sun in the shape of a long comet tail.

Jellyfish-shaped galaxy found in Abell 2670 cluster

Mon, 24 Apr 2017 09:00:01 EDT

(—Using the Multi Unit Spectroscopic Explorer (MUSE), astronomers have identified a new elliptical jellyfish-like galaxy in the Abell 2670 cluster. The newly detected galaxy showcases spectacular one-sided tails of gas and young stars, which indicates intense ram-pressure stripping. The findings were presented Apr. 18 in a paper published on the arXiv pre-print server.

Ancient stone pillars offer clues of comet strike that changed human history

Mon, 24 Apr 2017 08:40:01 EDT

(—A team of researchers with the University of Edinburgh has found what they describe as evidence of a comet striking the Earth at approximately the same time as the onset of the Younger Dryas in carvings on an ancient stone pillar in southern Turkey. The group has published their findings in the journal Mediterranean Archaeology and Archaeometry.

Cassini mission revealed Saturn's secrets

Mon, 24 Apr 2017 08:30:02 EDT

Cassini is the most sophisticated space probe ever built. Launched in 1997 as a joint NASA/European Space Agency mission, it took seven years to journey to Saturn.

A black hole in a low mass X-ray binary

Mon, 24 Apr 2017 06:01:41 EDT

A globular cluster is a roughly spherical ensemble of stars (as many as several million) that are gravitationally bound together, and typically located in the outer regions of galaxies. Low mass X-ray binary stars (LMXBs) are systems in which one star is compact (a neutron star or black hole) and is accreting matter from a companion star.

Studying interstellar dust from a balloon

Fri, 21 Apr 2017 09:00:03 EDT

In just a few days, the Pilot astrophysics experiment will be launched under a stratospheric balloon from Alice Springs in central Australia. Its aim is to observe the polarized emission of dust particles found in the interstellar medium of our galaxy and nearby galaxies.  With a mass approaching one metric ton, Pilot uses the largest balloons ever launched by CNES, the French national space agency. The experiment was developed by the Research Institute in Astrophysics and Planetology (CNRS/CNES/Paul Sabatier University), the Institute of Space Astrophysics (CNRS/Paris-Sud University), and the Institute of Research into the Fundamental Laws of the Universe (CEA-Irfu). The first Pilot flight was launched from Canada in September 2015; the forthcoming flight will thus be its first flight in the southern hemisphere sky, which contains more features of interest for Pilot than the northern hemisphere.
