  • Supermassive black holes feed on cosmic jellyfish
    on August 16, 2017 at 5:46 pm

    Observations of 'Jellyfish galaxies' with ESO's Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly. […]

  • Why massive galaxies don't dance in crowds
    on August 10, 2017 at 2:49 pm

    Scientists have discovered why heavyweight galaxies living in a dense crowd of galaxies tend to spin more slowly than their lighter neighbors. Contrary to earlier thinking, the spin rate of the galaxy is determined by its mass, rather than how crowded its neighborhood is. […]

  • New observations of Crab Nebula and Pulsar reveal polarized emissions
    on August 10, 2017 at 12:21 pm

    New observations of polarised X-rays from the Crab Nebula and Pulsar may help explain sudden flares in the Crab’s X-ray intensity, as well as provide new data for modeling – and understanding – the nebula. […]

  • The mystery of the pulsating blue stars
    on August 9, 2017 at 6:02 pm

    In the middle of the Chilean Atacama desert, a team of astronomers are monitoring millions of celestial bodies. In 2013, the team was surprised when they discovered, in the course of their survey, stars that pulsated much faster than expected. In the following years, the team studied these stars in more detail and concluded that they had stumbled upon a new class of variable star. […]

  • Twilight observations reveal huge storm on Neptune
    on August 3, 2017 at 7:22 pm

    Striking images of a storm system nearly the size of Earth have astronomers doing a double-take after pinpointing its location near Neptune's equator, a region where no bright cloud has been seen before. The discovery was made at dawn on June 26 as researchers were testing the Keck telescope to see whether it could make useful observations during twilight, a time most astronomers consider unusable because it's not dark enough. […]

  • Exoplanet shines with glowing water atmosphere
    on August 2, 2017 at 5:47 pm

    Scientists have found compelling evidence for a stratosphere on an enormous planet outside our solar system. The planet's stratosphere -- a layer of atmosphere where temperature increases with higher altitudes -- is hot enough to boil iron. […]

  • Running out of gas: Gas loss puts breaks on stellar baby boom
    on August 2, 2017 at 12:33 pm

    Understanding the history of star formation in the Universe is a central theme in modern astronomy. Various observations have shown that the star formation activity has varied through the 13.8 billion-year history of the Universe. The stellar birthrate peaked around 10 billion years ago, and has declined steadily since then. However, the cause of the declining stellar birthrate is still not well understood. […]

  • NASA continues to study pulsars, 50 years after their chance discovery
    on August 1, 2017 at 7:43 pm

    These rotating 'lighthouse' neutron stars begin their lives as stars between about seven and 20 times the mass of our sun. Some are found to spin hundreds of times per second, faster than the blades of a household blender, and they possess enormously strong magnetic fields. […]

  • Astronomers discover 'heavy metal' supernova rocking out
    on July 31, 2017 at 3:45 pm

    An extraordinarily bright supernova occurred in a surprising location, astronomers have found. This 'heavy metal' supernova discovery challenges current ideas of how and where such super-charged supernovas occur. In the past decade, astronomers have discovered about 50 supernovas, out of the thousands known, that are particularly powerful. Following the recent discovery of one of these, the researchers have uncovered vital clues about where some of these extraordinary objects come from. […]

  • Milky Way's origins are not what they seem
    on July 27, 2017 at 6:18 pm

    Up to half of the matter in our Milky Way galaxy may come from distant galaxies, astrophysicists have discovered in a first-of-its-kind analysis. As a result, each one of us may be made in part from extragalactic matter. Using supercomputer simulations, the researchers found an unexpected mode for how galaxies acquired matter: intergalactic transfer. Supernova explosions eject copious amounts of gas from galaxies, causing atoms to be transported from one galaxy to another via powerful galactic winds. […]

  • Galactic David and Goliath
    on July 27, 2017 at 2:30 pm

    The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Despite its diminutive size, NGC 1510 has had a significant effect on NGC 1512's structure and amount of star formation. […]

  • A tale of three stellar cities: Three different populations of baby stars
    on July 27, 2017 at 12:31 pm

    Using new observations from ESO's VLT Survey Telescope, astronomers have discovered three different populations of baby stars within the Orion Nebula Cluster. This unexpected discovery adds very valuable new insights for the understanding of how such clusters form. It suggests that star formation might proceeds in bursts, where each burst occurs on a much faster time-scale than previously thought. […]

  • Dawn of the cosmos: Seeing galaxies that appeared soon after the Big Bang
    on July 26, 2017 at 6:33 pm

  • Gamma-ray burst captured in unprecedented detail
    on July 26, 2017 at 5:21 pm

    Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date. […]

  • Superluminous supernova marks the death of a star at cosmic high noon
    on July 21, 2017 at 4:25 pm

    The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak. […]
