Mapping out Earth's place in the universe among 'Council of Giants'
We live in a galaxy known as the Milky Way – a vast conglomeration of 300 billion stars, planets whizzing around them, and clouds of gas and dust floating in between.
These aren’t the voids you’re looking for
Australian astronomers have shown galaxies in the vast empty regions of the Universe are actually aligned into delicate strings in research published today in the Monthly Notices of the Royal Astronomical Society.
Lava floods the ancient plains of Mars
Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found.
‘Death Stars’ in Orion blast planets before they even form
The Orion Nebula is home to hundreds of young stars and even younger protostars known as proplyds. Many of these nascent systems will go on to develop planets, while others will have their planet-forming dust and gas blasted away by the fierce ultraviolet radiation emitted by massive O-type stars that lurk nearby.
A small step toward discovering habitable earths
University of Arizona researchers snapped images of a planet outside our solar system with an Earth-based telescope using essentially the same type of imaging sensor found in digital cameras instead of an infrared detector. Although the technology still has a very long way to go, the accomplishment takes astronomers a small step closer to what will be needed to image earth-like planets around other stars.
Nearby star's icy debris suggests 'Shepherd' planet
An international team of astronomers exploring the disk of gas and dust around a nearby star have uncovered a compact cloud of poisonous gas formed by ongoing rapid-fire collisions among a swarm of icy, comet-like bodies. The researchers suggest the comet swarm is either the remnant of a crash between two icy worlds the size of Mars or frozen debris trapped and concentrated by the gravity of an as-yet-unseen planet.
NASA's THEMIS discovers new process that protects Earth from space weather
In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay.
Hubble witnesses an asteroid mysteriously disintegrating
The NASA/ESA Hubble Space Telescope has photographed the never-before-seen break-up of an asteroid, which has fragmented into as many as ten smaller pieces. Although fragile comet nuclei have been seen to fall apart as they approach the Sun, nothing like the breakup of this asteroid, P/2013 R3, has ever been observed before in the asteroid belt.
Chandra and XMM-Newton provide direct measurement of distant black hole's spin
Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly. This first direct measurement of the spin of such a distant black hole is an important advance for understanding how black holes grow over time.
Mystery of planet-forming disks explained by magnetism
Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.
NASA tests new robotic refueling technologies
NASA has successfully concluded a remotely controlled test of new technologies that would empower future space robots to transfer hazardous oxidizer – a type of propellant – into the tanks of satellites in space today.
Galactic gas stations
Future lunar missions may be fueled by gas stations in space, according to MIT engineers: A spacecraft might dock at a propellant depot, somewhere between the Earth and the moon, and pick up extra rocket fuel before making its way to the lunar surface.
Claim: Bright pulses of light could make space veggies more nutritious
Exposing leafy vegetables grown during spaceflight to a few bright pulses of light daily could increase the amount of eye-protecting nutrients produced by the plants, according to a new study by researchers at the University of Colorado Boulder.
NASA's Hubble finds life is too fast, furious for runaway galaxy
The spiral galaxy ESO 137-001 looks like a dandelion caught in a breeze in this new Hubble Space Telescope image.
Spiral galaxy spills blood and guts
This new Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. This cluster is violently ripping the spiral’s entrails out into space, leaving bright blue streaks as telltale clues to this cosmic crime.
NASA takes on cancer with space station research
Invasive and systemic cancer treatment is a necessary evil for many people with the devastating diagnosis. These patients endure therapies with ravaging side effects, including nausea, immune suppression, hair loss and even organ failure, in hopes of eradicating cancerous tissues in the body.
It’s a march of the CubeSats as space station deployment continues
It’s a bird, it’s a plane, it’s a CubeSat! With so many small, relatively inexpensive satellites deploying lately from the International Space Station, it may seem like the area referred to as low-Earth orbit, between 100 and 1,240 miles above the planet, is full of these compact cubes. The miniature satellites, or CubeSats, conduct research and demonstration missions.
Touchy-feely joystick headed to International Space Station (ISS)
Stowed inside ESA’s next supply ship to the International Space Station will be one of the most advanced joysticks ever built, designed to test the remote control of robots on the ground from up in orbit.
New fast and furious black hole found
A team of Australian and American astronomers have been studying nearby galaxy M83 and have found a new superpowered small black hole, named MQ1, the first object of its kind to be studied in this much detail.
Detection of water vapor in the atmosphere of a hot jupiter
Although liquid water covers a majority of Earth's surface, scientists are still searching for planets outside of our solar system that contain water. Researchers at Caltech and several other institutions have used a new technique to analyze the gaseous atmospheres of such extrasolar planets and have made the first detection of water in the atmosphere of the Jupiter-mass planet orbiting the nearby star tau Boötis.
