New ESO Image of Star Cluster NGC 3532

This new ESO image shows bright star cluster NGC 3532, which is located roughly 1,300 light-years away. NGC 3532 is a bright open cluster located some 1,300 light-years away in the constellation of Carina (The Keel of the ship Argo). It is informally known as the Wishing Well Cluster, as it resembles scattered silver coins […]

Scientists Estimate the Magnetic Field of an Exoplanet

A team of scientists has developed a new method that allows them to estimate the magnetic field of a distant exoplanets. Using this method they managed to estimate the value of the magnetic moment of the planet HD 209458b. In the two decades which passed since the discovery of the first planet outside the Solar […]

Solar Nebula Magnetic Fields Recorded in the Semarkona Meteorite

Scientists from the Harvard-Smithsonian Center for Astrophysics have succeeded in determining ancient solar nebula magnetic field strength by measuring the field recorded in chondrules from the Semarkona meteorite. Astronomical observations of young protostars indicate that early planetary systems evolved from the dust in a protoplanetary disk very quickly – in under five million years. Such […]

Chandra Image of Supernova Remnant MSH 11-62

New observations from NASA’s Chandra X-ray Observatory reveal details of supernova remnant MSH 11-62 and G327.1-1.1. A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of high-energy […]

High-Resolution Images of Markarian 177 and SDSS1133

Using data from NASA’s Swift satellite and observations from many other facilities, an international team of astronomers has discovered an unusual source of light in a galaxy some 90 million light-years away. The object’s curious properties make it a good match for a supermassive black hole ejected from its home galaxy after merging with another […]

Gravity May Have Saved the Universe

A newly published study details how the spacetime curvature provided the stability needed for the universe to survive after the Big Bang. Studies of the Higgs particle – discovered at CERN in 2012 and responsible for giving mass to all particles – have suggested that the production of Higgs particles during the accelerating expansion of […]

Mysterious Alignment of Quasars

Using data from ESO’s Very Large Telescope, astronomers have discovered alignments between supermassive black hole axes separated by billions of light-years. New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the […]

Intergalactic Wind is Stripping Galaxies of Gas

A newly published study provides the first direct evidence that an intergalactic “wind” is stripping galaxies of star-forming gas as they fall into clusters of galaxies, helping explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or “field” galaxies. Toronto, Ontario – Astronomers […]

The Future of Neutrino Cosmology

An international team of scientists has published an extensive report on the future of astrophysical neutrino measurements, discussing how facilities that measure the microwave background will in the next decade also enable scientists to study the nature of neutrinos, and lead to fundamental insights into the basic laws of nature. One of the most remarkable […]

Study Finds That a Strong Magnetic Field Shaped the Early Solar System

New research reveals the first experimental evidence that our solar system’s protoplanetary disk was shaped by an intense magnetic field that drove a massive amount of gas into the sun within just a few million years. Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a […]

Astronomers Discover Massive Compact Galaxies with High-Velocity Outflows

Astronomers investigate the process of rapid star formation in 12 massive galaxies that host high-velocity ionized gas outflows, finding that these fast outflows are most likely driven by feedback from star formation rather than active galactic nuclei (AGN). Researchers using NASA’s Hubble Space Telescope and Chandra X-ray Observatory have uncovered young, massive, compact galaxies whose […]

Telescopes Reveal That a Black Hole May Be a Neutrino Factory

Using three NASA satellites, astronomers have revealed the first evidence that the Milky Way’s supermassive black hole (Sagittarius A*) may be producing neutrinos. The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back […]

Evidence of Galactic Merger in Distant Protocluster

Using the Atacama Large Millimeter/submillimeter Array, astronomers show a clear picture of hierarchical merging and the all-important first steps along this process when the Universe was only 8 percent of its current age. Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing […]
