Dark matter may not be completely dark after all.
For the first time dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies made with ESO’s Very Large Telescope and the NASA/ESA Hubble Space Telescope have picked up the first intriguing hints about the nature of this mysterious component of the Universe.
A lag between dark matter and its associated galaxy is predicted during collisions i [...]
It's stars versus dust in the Carina Nebula and the stars are winning. More precisely, the energetic light and winds from massive newly formed stars are evaporating and dispersing the dusty stellar nurseries in which they formed. Located in the Carina Nebula and known informally as Mystic Mountain, these pillar's appearance is dominated by the dark dust even though it is composed mostly of clear hydrogen gas.
Dust pillars such as these are actually much thinner than air and only appear as mo [...]
SpaceX will attempt another launch today at 4:10 p.m. EDT after a weather violation within 10 nautical miles of the launch pad at Cape Canaveral, Florida, forced mission controllers to scrub Monday’s launch of the SpaceX Falcon 9 rocket carrying the Dragon space freighter to the International Space Station. Live coverage on NASA TV begins at 3 p.m.
The six Expedition 43 crew members aboard the orbital laboratory worked on a wide variety of microgravity science Tuesday. The crew also worked [...]
NASA’s New Horizons spacecraft is three months from returning to humanity the first-ever close up images and scientific observations of distant Pluto and its system of large and small moons.
"Scientific literature is filled with papers on the characteristics of Pluto and its moons from ground based and Earth orbiting space observations, but we’ve never studied Pluto up close and personal,” said John Grunsfeld, astronaut, and associate administrator of the NASA Science Mission Directorat [...]
Cambridge, MA - NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known.
The discovery demonstrates that Spitzer - from its unique perch in space - can be used to help solve the puzzle of how planets are distributed throughout our flat, spiral-shaped Milky Way galaxy. Are they concentrated heavily in its central hub, or more evenly spread throughout its suburbs?

Vulcan Name Chosen by America with more than 1 Million Online Votes Cast.
Colorado Springs, Colo. -- United Launch Alliance (ULA) unveiled its Next Generation Launch System (NGLS) today at the 31st Space Symposium. The new rocket, Vulcan, will transform the future of space by making launch services more affordable and accessible. The NGLS brings together dec [...]
SpaceX is ready to launch its Falcon 9 rocket and Dragon space freighter today at 4:33 p.m. EDT loaded with more than two tons of science gear and crew supplies. Orbiting overhead in the International Space Station the six Expedition 43 crew members observed Cosmonautics Day.
NASA TV will cover the launch of the sixth SpaceX Commercial Resupply Services mission (SpaceX CRS-6) live beginning at 3:30 p.m. today. The Dragon spacecraft will arrive at the space station Wednesday morning for a five [...]
The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:
1. Monday, April 13, 2015, 2-3:30 PM PDT (21-22:30 GMT)
DR. ERIK CONWAY comes to the show to discuss his latest book "Exploration and Engineering: The Jet Propulsion Laboratory and the Quest for Mars ( New Series in NASA History."
Erik M. Conway is the historian at NASA's Jet Propulsion Laboratory at the California Institute of Technology in Pasadena. He is the author of severa [...]
The view was worth the trip. Battling high winds, cold temperatures, and low oxygen, the trek to near the top of the volcano Santa Maria in Guatemala -- while carrying sensitive camera equipment -- was lonely and difficult. Once set up, though, the camera captured this breathtaking vista during the early morning hours of February 28.
Visible on the ground are six volcanoes of the Central America Volcanic Arc, including Fuego, the Volcano of Fire, which is seen erupting in the distance. Visib [...]
Who guards the north? Judging from the above photograph, possibly giant trees covered in snow and ice. The featured picture was taken a few winters ago in Finnish Lapland where weather can include sub-freezing temperatures and driving snow. Surreal landscapes sometimes result, where common trees become cloaked in white and so appear, to some, as watchful aliens.
Far in the distance, behind this uncommon Earthly vista, is a more common sight -- a Belt of Venus that divided a darkened from sun [...]
In the coming days, Venus shines near the western horizon at sunset. To find Earth's sister planet in twilight skies just look for the brilliant evening star. Tonight very close to the Pleiades star cluster, Venus dominates this springtime night skyscape taken only a few days ago near the town of Lich in central Germany.
Also known as the Seven Sisters, the stars of the compact Pleiades cluster appear above Venus in this picture. The budding tree branches to its left frame bright star Aldeba [...]
This image shows the center of the globular cluster Messier 22, also known as M22, as observed by the NASA/ESA Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 billion years old.
Messier 22 is one of about 150 globular clusters in the Milky Way and at just 10,000 light-years away it is also one of the [...]
Barred spiral galaxy NGC 2903 is only some 20 million light-years distant. Popular among amateur astronomers, it shines in the northern spring constellation Leo, near the top of the lion's head. That part of the constellation is sometimes seen as a reversed question mark or sickle. One of the brighter galaxies visible from the northern hemisphere, NGC 2903 is surprisingly missing from Charles Messier's catalog of lustrous celestial sights.
This colorful image from a small ground-based telesc [...]
In one of the most comprehensive multi-observatory galaxy surveys yet, astronomers find that galaxies like our Milky Way underwent a stellar “baby boom,” churning out stars at a prodigious rate, about 30 times faster than today.
Our sun, however, is a late “boomer.” The Milky Way’s star-birthing frenzy peaked 10 billion years ago, but our sun was late for the party, not forming until roughly 5 billion years ago. By that time the star formation rate in our galaxy had plunged to a tri [...]
More life science work took place Thursday aboard the International Space Station as scientists study the effects of living in space during a long term space mission. Back on Earth, SpaceX is counting down to a Monday launch of its Dragon space freighter.
More eye checks took place Thursday as the crew in the U.S. segment of the orbital lab participated in a series of week-long Ocular Health activities. The crew also conducted artery scans using an Ultrasound for the Cardio Ox inflammatory st [...]
While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable – a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions.
Our sun steadily emits light, energy and a constant flow of particles called the solar wind that bathes the planets as it travels out into space. Larger eruptions of solar material, called coronal mass ejections, [...]
Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water.
New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers. It is the equivalent of all of Mars being covered by more than one me [...]
