Hubble Views Polar Ring Galaxy NGC 660

Hubble Views Polar Ring Galaxy NGC 660

This newly released Hubble image shows polar ring galaxy NGC 660, which is thought to harbor exceptionally large amounts of dark matter. This new Hubble image shows a peculiar galaxy known as NGC 660, located around 45 million light-years away from us. NGC 660 is classified as a “polar ring galaxy”, meaning that it has […]

Cassini Views Titan’s South Polar Vortex

Cassini Views Titan

NASA’s Cassini spacecraft views Titan, Saturn’s largest moon. The sunlit edge of Titan’s south polar vortex stands out distinctly against the darkness of the moon’s unilluminated hazy atmosphere. The Cassini spacecraft images of the vortex led scientists to conclude that its clouds form at a much higher altitude – where sunlight can still reach – […]

Nanoengineers Develop ‘Nanosponge Vaccine’ to Fight MRSA Toxins

Scientists Develop Nanosponges That Fight MRSA Toxins

Nanoengineers from UC San Diego have developed nanosponges that soak up a dangerous pore-forming toxin produced by MRSA, and have shown that their nanosponge vaccine was safe and more effective than toxoid vaccines made from heat-treated staph toxin. Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as […]

Scientists Rethink How Neutron Stars Heat Up

Researchers Rethink the Mystery of Neutron Stars

A newly published study details how the surface of a neutron star heats up, identifying previously unknown layers where nuclear reactions within the crust cause rapid neutrino cooling. Until now, scientists were pretty sure they knew how the surface of a neutron star – a super dense star that forms when a large star explodes […]

Hubble Views Irregular Galaxy 149-3

Hubble Views Irregular Galaxy ESO 149 3

In this image NASA’s Hubble Space Telescope views irregular galaxy ESO 149-3 and other more distant galaxies. This sprinkling of cosmic glitter makes up the galaxy known as ESO 149-3, located some 20 million light-years away from us. It is an example of an irregular galaxy, characterized by its amorphous, undefined shape — a property […]

Computer Simulations Show How Stars at the Center of the Milky Way Move

Study Reveals How Stars Move at the Center of the Galaxy

In a newly published study, researchers from the University of Rochester use computer simulations to show how the stars at the center of the Milky Way move in a peanut-shell shaped orbits. Two months ago astronomers created a new 3D map of stars at the center of our Galaxy (the Milky Way), showing more clearly […]

An Unexpected Discovery in Galaxy Messier 101

Composite Image of M101

Using data from the Gemini Observatory, researchers discovered that a small black hole can sustain a hugely voracious appetite while consuming material in an efficient and tidy manner – something previously thought impossible. Observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light-years away could change our thinking […]

NASA Image of the Day – Black Holes Have Simple Feeding Habits

A Supermassive Black Hole in M81

The NASA image of the day shows the supermassive black hole at the center of spiral galaxy M81. At the center of spiral galaxy M81 is a supermassive black hole about 70 million times more massive than our sun. A study using data from Chandra and ground-based telescopes, combined with detailed theoretical models, shows that […]

Volunteers Discover Four Cosmic Lighthouses in Fermi Data

Volunteers Discover Cosmic Lighthouses in Fermi Data

Using the distributed computing project [email protected], international volunteers discover four cosmic lighthouses in data from NASA’s Fermi gamma-ray space telescope. The combination of globally distributed computing power and innovative analysis methods proves to be a recipe for success in the search for new pulsars. Scientists from the Max Planck Institutes for Gravitational Physics and Radio […]

ESO’s Very Large Telescope Views the Dragon’s Head Nebula

ESOs Very Large Telescope Explores NGC 2035

A new ESO image explores the Large Magellanic Cloud and an area nicknamed the Dragon’s Head Nebula. The Large Magellanic Cloud is one of the closest galaxies to our own. Astronomers have now used the power of ESO’s Very Large Telescope to explore one of its lesser known regions. This new image shows clouds of […]

Astronomers Search for Medium-Sized Black Holes

NuSTAR Studies Black Holes

In two new studies, astronomers examine black holes in the Circinus galaxy and spiral galaxy NGC 1313, searching for evidence of medium-sized black holes. Black holes can be petite, with masses only about 10 times that of our sun — or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black holes […]

Reverse Shock Wave Racing Inward at 1000 Times the Speed of Sound

Reverse Shock Wave Racing Inward at 1000 Times the Speed of Sound

Researchers from the Harvard-Smithsonian Center for Astrophysics have discovered that a reverse shock wave racing inward at 1000 times the speed of sound is heating the Tycho supernova remnant and causing it to emit X-ray light. Cambridge, Massachusetts – When a star explodes as a supernova, it shines brightly for a few weeks or months […]

Aerospace Engineers Discover a Possible Fix for the Kepler Spacecraft

A Possible Fix for Kepler Spacecraft

Kepler mission and Ball Aerospace engineers believe they have figured out how to get the Kepler Spacecraft working again. By maneuvering the spacecraft so that the solar pressure is evenly distributed across the surfaces of the spacecraft, they believe the Sun can as the ‘third wheel’ to control pointing. You may have thought that NASA’s […]

Hubble Views Spiral Galaxy NGC 4921

New Hubble Image of Spiral Galaxy NGC 4921

This new Hubble image shows spiral galaxy NGC 4921. How far away is spiral galaxy NGC 4921? Although presently estimated to be about 310 million light years distant, a more precise determination could be coupled with its known recession speed to help humanity better calibrate the expansion rate of the entire visible universe. Toward this […]
