This neat little galaxy is known as NGC 4526. Its dark lanes of dust and bright diffuse glow make the galaxy appear to hang like a halo in the emptiness of space in this image from the NASA/ESA Hubble Space Telescope.
Although this image paints a picture of serenity, the galaxy is anything but. It is one of the brightest lenticular galaxies known, a category that lies somewhere between spirals and ellipticals. It has hosted two known supernova explosions, one in 1969 and another in 1994, and [...]
MOSCOW - China has launched an unmanned spacecraft, named Chang’e-5, on Friday, with hopes the probe will carry out the country’s first mission to the Moon and back, CCTV reported.
The mission is aimed at testing technologies which are vital for the success of the country’s first lunar mission which will return to the Earth.
The launch of Chang’e-5 took place at 18:00 UTC. The lunar orbiter was carried by an advanced Long March-3C launch vehicle from the LC2 launch complex of the X [...]
As you (safely!) watched the progress of yesterday's partial solar eclipse, you probably also spotted a giant sunspot group. Captured in this sharp telescopic image from October 22nd the complex AR 2192 is beautiful to see, a sprawling solar active region comparable in size to the diameter of Jupiter.
Like other smaller sunspot groups, AR 2192 is now crossing the Earth-facing side of the Sun and appears dark in visible light because it is cooler than the surrounding surface. Still, the energ [...]
Four NASA sponsored experiments were provided nearly four minutes of microgravity flight and testing after UP Aerospace's SpaceLoft rocket SL-9 soared into suborbital space from Spaceport America outside of Las Cruces, New Mexico on Thursday.
While flying on suborbital launch vehicles in zero gravity, experimental technologies are briefly exposed to the space environment where they are expected to operate.
Both Game Changing and Flight Opportunities Programs are part of the agency's Spac [...]
Closest near-miss event to be spotted near the Milky Way.
COLUMBUS, Ohio: Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.
We may think of black holes as swallowing entire stars—or any other object that wanders too close to their immense gravity. But sometimes, a star that is almost captured by a black hole escapes with only a portion of its mass torn off. Such was the case for a star some [...]
This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.
The comet image shown here is a composite of Hubble exposures taken between O [...]
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft obtained this ultraviolet image of hydrogen surrounding comet Siding Spring on Friday, Oct. 17, two days before the comet’s closest approach to Mars. The Imaging Ultraviolet Spectrograph (IUVS) instrument imaged the comet at a distance of 5.3 million miles (8.5 million kilometers).
The image shows sunlight that has been scattered by atomic hydrogen, and is shown as blue in this false-color representation. Comets are surround [...]
Although scientists have flown two spacecraft in formation, no one ever has aligned the spacecraft with a specific astronomical target and then held that configuration to make a scientific observation — creating, in effect, a single or “virtual” telescope with two distinctly different satellites.
A NASA team, led by aerospace engineer Neerav Shah of NASA's Goddard Space Flight Center in Greenbelt, Maryland, is not only developing the guidance, navigation, and control (GN&C) technol [...]
On Oct. 18, 2014, a sunspot rotated over the left side of the sun, and soon grew to be the largest active region seen in the current solar cycle, which began in 2008. Currently, the sunspot is almost 80,000 miles across -- ten Earth's could be laid across its diameter.
Sunspots point to relatively cooler areas on the sun with intense and complex magnetic fields poking out through the sun's surface. Such areas can be the source of solar eruptions such as flares or coronal mass ejections. So [...]
