Have you ever seen the Summer Triangle? The bright stars Vega, Deneb, and Altair form a large triangle on the sky that can be seen rising in the early northern early spring during the morning and rising in the northern fall during the evening.
During summer months, the triangle can be found nearly overhead near midnight. Featured here, the Summer Triangle asterism was captured last month from Gunma, Japan. In the foreground, sporting a triangular shape of its own, is a flowering 500 year old [...]
An international team of astronomers, led by Yale University and University of California scientists, has pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age of 13.8 billion years.
The team discovered an exceptionally luminous galaxy more than 13 billion years in the past and determined its exact distance from Earth using the combined data from NASA's Hubble and Spitzer space telescopes, and the Keck I 10-meter telescope at [...]
NASA astronauts Terry Virts and Scott Kelly spent the day replacing components inside one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.
ESA astronaut Samantha Cristoforetti continued two experiments that are investigating how the body changes while in microgravity. The Triplelux-A experiment aims to gain a better understanding of immune suppression in spaceflight [...]
Crew Dragon's first critical flight test, known as a Pad Abort Test, is expected to take place this Wednesday, May 6, from SpaceX’s Space Launch Complex 40 (SLC-40) in Cape Canaveral, Florida. While the test is originating from the same launch pad we use for operational missions, this is not an operational flight.
This will be the first flight test of SpaceX’s revolutionary new launch abort system, and the odds of encountering delays or issues are high. Fortunately the test doesn’t ne [...]
NASA has beefed up a process of traffic monitoring, communication and maneuver planning to ensure that Mars orbiters do not approach each other too closely.
Last year's addition of two new spacecraft orbiting Mars brought the census of active Mars orbiters to five, the most ever. NASA's Mars Atmosphere and Volatile Evolution (MAVEN) and India's Mars Orbiter Mission joined the 2003 Mars Express from ESA (the European Space Agency) and two from NASA: the 2001 Mars Odyssey and the 2006 Mars Rec [...]
What's that under the surface of Mercury? The robotic MESSENGER spacecraft that had been orbiting planet Mercury for the past four years had been transmitting its data back to Earth with radio waves of very precise energy. The planet's gravity, however, slightly changed this energy when measured on Earth, which enabled the reconstruction of a gravity map of unprecedented precision.
Here gravitational anomalies are shown in false-color, superposed on an image of the planet's cratered surface. [...]
Monday began a new week of science and maintenance work for the Expedition 43 crew.
NASA astronauts Terry Virts and Scott Kelly spent the day reviewing procedures and gathering equipment for an upcoming replacement activity with one of the station’s Carbon Dioxide Removal Assemblies (CDRA.) The CDRA system works to remove carbon dioxide from the cabin air, allowing for an environmentally safe crew cabin.
ESA astronaut Samantha Cristoforetti participated in the Skin-B experiment which wil [...]
The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:
1. Monday, May 4, 2015, 2-3:30 PM PDT (21-22:30 GMT)
BRUCE PITTMAN comes to the show to discuss ISDC 2015 (http://isdc2015.nss.org/wordpress).
Bruce Pittman is the Director, Flight Projects and Chief System Engineer at the Space Portal, NASA Ames Research Center where he supports commercial space efforts including both Commercial Reusable Suborbital Research (CRuSR) and lunar [...]
Sometimes the sky lights up unexpectedly. A trip to northern Norway to photograph auroras was not going as well as hoped. It was now past midnight in Steinsvik, Troms, in northern Norway, and the date was 2014 February 8. Despite recent activity on the Sun, the skies were disappointing. Therefore, the astrophotographer began packing up to go. His brother began searching for a missing lens cap.
When the sky suddenly exploded with spectacular aurora. Reacting quickly, a sequence detailing dram [...]
How can the Moon rise through a mountain? It cannot -- what was photographed here is a moonrise through the shadow of a large volcano. The volcano is Mauna Kea, Hawai'i, USA, a frequent spot for spectacular photographs since it is arguably the premier observing location on planet Earth. The Sun has just set in the opposite direction, behind the camera. Additionally, the Moon has just passed full phase -- were it precisely at full phase it would rise, possibly eclipsed, at the very peak of the sh [...]
Follow the handle of the Big Dipper away from the dipper's bowl until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier famous catalog.
Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (right), NGC 5195. [...]
A team of highly determined high school students discovered a never-before-seen pulsar by painstakingly analyzing data from the National Science Foundation’s (NSF) Robert C. Byrd Green Bank Telescope (GBT). Further observations by astronomers using the GBT revealed that this pulsar has the widest orbit of any around a neutron star and is part of only a handful of double neutron star systems.
This impressive find will help astronomers better understand how binary neutron star systems form an [...]
The Australian discovery of a strange exoplanet orbiting a small cool star 500 light years away is challenging ideas about how planets form.
"We have found a small star, with a giant planet the size of Jupiter, orbiting very closely," said researcher George Zhou from the Research School of Astrophysics and Astronomy.
Subsequent observations from the Chilean telescope, and spectra taken from the ANU 2.3 metre telescope at Siding Spring, confirmed the planet had an orbit of just one-tenth [...]
The following is a statement from NASA Administrator Charles Bolden on the House of Representatives’ NASA authorization bill:
"The NASA authorization bill making its way through the House of Representatives guts our Earth science program and threatens to set back generations worth of progress in better understanding our changing climate, and our ability to prepare for and respond to earthquakes, droughts, and storm events.
“NASA leads the world in the exploration of and study of p [...]
The first to orbit Mercury, the MESSENGER spacecraft came to rest on this region of Mercury's surface yesterday. Constructed from MESSENGER image and laser altimeter data, the scene looks north over the northeastern rim of the broad, lava filled Shakespeare basin. The large, 48 kilometer (30 mile) wide crater Janacek is near the upper left edge. Terrain height is color coded with red regions about 3 kilometers above blue ones.
MESSENGER'S final orbit was predicted to end near the center, wit [...]
A NASA planetary exploration mission came to a planned, but nonetheless dramatic, end Thursday when it slammed into Mercury’s surface at about 8,750 mph and created a new crater on the planet’s surface.
Mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, have confirmed NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft impacted the surface of Mercury, as anticipated, at 3:26 p.m. EDT.
A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study using NASA’s Chandra X-ray Observatory. This finding may help astronomers understand how the largest black holes were able to grow so rapidly in the early Universe.
Astronomers have known for some time that supermassive black holes − with masses ranging from millions to billions of times the mass of the Sun and residing at the centers of galaxies − can gobble up huge quantities of [...]
Station astronauts continued preparing for the next round of robotic refueling demonstrations while conducting various biomedical experiments and checkouts.
Expedition 43 commander Terry Virts worked with ground teams to prepare the airlock in the Japanese Experiment Module and extend the slide table carrying the new Robotic Refueling Mission-2 (RRM-2) hardware. Robotics controllers on the ground then used the Canadarm2 robotic arm to install the new task boards that will be used for the expe [...]
