Approaching opposition early next month, Jupiter is offering some of its best telescopic views from planet Earth. On March 17, this impressively sharp image of the solar system's ruling gas giant was taken from a remote observatory in Chile. Bounded by planet girdling winds, familiar dark belts and light zones span the giant planet spotted with rotating oval storms.
The solar system's largest moon Ganymede is above and left in the frame, its shadow seen in transit across the northern Jovian [...]
Expedition 50 Commander Shane Kimbrough of NASA and Flight Engineer Thomas Pesquet of ESA (European Space Agency concluded their spacewalk at 1:58 p.m. EDT. During the spacewalk, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections on the Pressurized Mating Adapter-3 to prepare for its robotic move Sunday, March 26.
The PMA-3 provides the pressurized interface between the station modules and the International Docking Adapt [...]
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
Though there have been several other suspected, similarly booted black holes elsewhere, none has been confirmed so far. Astronomers think this object, detected by NASA's Hubble Space Telescope, is a very strong case. Weighing more than 1 billion suns, the rogue black hole is the most massive black hole ever detected to ha [...]
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age. These progenitors of today’s giant spiral galaxies are surrounded by "super halos" of hydrogen gas that extend many tens of thousands of light-years beyond their dusty, star-filled disks.
Astronomers initially detected these galaxies by studying the intense ligh [...]
Comet 41P/Tuttle-Giacobini-Kresak poses for a Messier moment in this telescopic snapshot from March 21. In fact it shares the 1 degree wide field-of-view with two well-known entries in the 18th century comet-hunting astronomer's famous catalog. Sweeping through northern springtime skies just below the Big Dipper, the faint greenish comet was about 75 light-seconds from our fair planet. Dusty, edge-on spiral galaxy Messier 108 (bottom center) is more like 45 million light-years away.
At upper [...]
The Milky Way's closest neighbor, Andromeda, features a dominant source of high-energy X-ray emission, but its identity was mysterious until now. As reported in a new study, NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission has pinpointed an object responsible for this high-energy radiation.
The object, called Swift J0042.6+4112, is a possible pulsar, the dense remnant of a dead star that is highly magnetized and spinning, researchers say. This interpretation is based on its emis [...]
Two astronauts are getting the Quest airlock and their equipment ready for a Friday morning spacewalk. The cosmonauts continued their human research program today exploring the various affects of living in space.
Spacewalkers Shane Kimbrough and Thomas Pesquet will exit the Quest airlock Friday at 8 a.m. EDT to begin setting up the International Space Station for future commercial crew missions. The duo will work outside for about 6.5 hours on the first of three spacewalks scheduled to take p [...]
This skyscape features dusty Sharpless catalog emission region Sh2-155, the Cave Nebula. In the telescopic image, data taken through a narrowband filter tracks the reddish glow of ionized hydrogen atoms. About 2,400 light-years away, the scene lies along the plane of our Milky Way Galaxy toward the royal northern constellation of Cepheus.
Astronomical explorations of the region reveal that it has formed at the boundary of the massive Cepheus B molecular cloud and the hot, young stars of the [...]
The astronauts took a break from spacewalk preparations today and checked out an expandable module and worked on science freezers. The crew also continued its human research program exploring space nutrition and the effects of microgravity on metabolism and the immune system.
Thomas Pesquet opened the hatches to the Bigelow Expandable Activity Module (BEAM) today for a status check. The European Space Agency astronaut sampled BEAM’s air and surfaces for microbes and installed impact sensors [...]
Dwarf planet Ceres may be hundreds of millions of miles from Jupiter, and even farther from Saturn, but the tremendous influence of gravity from these gas giants has an appreciable effect on Ceres' orientation. In a new study, researchers from NASA's Dawn mission calculate that the axial tilt of Ceres -- the angle at which it spins as it journeys around the sun -- varies widely over the course of about 24,500 years. Astronomers consider this to be a surprisingly short period of time for such dra [...]
In cosmic brush strokes of glowing hydrogen gas, this beautiful skyscape unfolds across the plane of our Milky Way Galaxy near the northern end of the Great Rift and the center of the constellation Cygnus the Swan. A 36 panel mosaic of telescopic image data, the scene spans about six degrees. Bright supergiant star Gamma Cygni (Sadr) to the upper left of the image center lies in the foreground of the complex gas and dust clouds and crowded star fields.
Left of Gamma Cygni, shaped like two lu [...]
Three astronauts are preparing for a Friday morning spacewalk to upgrade and maintain the International Space Station’s external systems. The three cosmonauts stayed focused today on their set of Russian space experiments and life support work.
Astronauts Shane Kimbrough of NASA and Thomas Pesquet from the European Space Agency are reviewing procedures for the spacewalk set to begin Friday at 8 a.m. EDT with live NASA TV coverage at 6:30 a.m. NASA astronaut Peggy Whitson joined the pair for [...]
Start with the constellation of Orion. Below Orion's belt is a fuzzy area known as the Great Nebula of Orion. In this nebula is a bright star cluster known as the Trapezium, marked by four bright stars near the image center. The newly born stars in the Trapezium and surrounding regions show the Orion Nebula to be one of the most active areas of star formation to be found in our area of the Galaxy.
In Orion, supernova explosions and close interactions between stars have created rogue planets [...]
Some 290 million years ago, a star much like the sun wandered too close to the central black hole of its galaxy. Intense tides tore the star apart, which produced an eruption of optical, ultraviolet and X-ray light that first reached Earth in 2014. Now, a team of scientists using observations from NASA's Swift satellite have mapped out how and where these different wavelengths were produced in the event, named ASASSN-14li, as the shattered star's debris circled the black hole.
"We discovered [...]
The Expedition 50 crew is gearing up for three spacewalks over two weeks to continue the external maintenance at the International Space Station. Also, the SpaceX Dragon is returning to port today after completing a month-long stay at the station.
Astronauts Shane Kimbrough and Thomas Pesquet will begin the first spacewalk Friday at 8 a.m. EDT. NASA TV will begin live coverage of the 198th spacewalk in support of station assembly and maintenance Friday at 6:30 a.m.
The two spacewalkers wil [...]
As children, we learned about our solar system's planets by certain characteristics -- Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. Mars is red, but it's possible that one of our closest neighbors also had rings at one point and may have them again someday.
That's the theory put forth by NASA-funded scientists at Purdue University, Lafayette, Indiana, whose findings were published in the journal Nature Geoscience. David Minton and Andrew Hesselbrock developed a mod [...]
Yes, but can your tree do this? Pictured is a visual coincidence between the dark branches of a nearby tree and bright glow of a distant aurora. The beauty of the aurora -- combined with how it seemed to mimic a tree right nearby -- mesmerized the photographer to such a degree that he momentarily forgot to take pictures.
When viewed at the right angle, it seemed that this tree had aurora for leaves! Fortunately, before the aurora morphed into a different overall shape, he came to his senses [...]
