Astronomy Picture Of the Day (APOD)
Rocket, Meteor, and Milky Way over Thailand
12.02.2014
Can the night sky appear both serene and surreal? Perhaps classifiable as serene in the above panoramic image taken last Friday are the faint lights of small towns glowing across a dark foreground landscape of Doi Inthanon National Park in Thailand, as well as the numerous stars glowing across a dark background starscape.
The Heart and Soul Nebulas
11.02.2014
Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805 and visible in the above zoomable view on the right, has a shape reminiscent of a classical heart symbol.
Falling to Earth
10.02.2014
What would it be like to fall to Earth from really high up? A new record for the highest jump was accomplished in 2012 by Felix Baumgartner. Surpassing the previous record of 31.3 kilometer...
The Missing Craters of Asteroid Itokawa
9.02.2014
Where are the craters on asteroid Itokawa? Missing -- unexpectedly. The Japanese robot probe Hayabusa approached the Earth-crossing asteroid in 2005 and returned pictures showing a surface unlike any other Solar System body yet photographed -- a surface possibly devoid of craters.
NGC 5101 and Friends
8.02.2014
This sharp telescopic field of view holds two bright galaxies. Barred spiral NGC 5101 (top right) and nearly edge-on system NGC 5078 are separated on the sky by about 0.5 degrees or about the apparent width of a full moon.
Night Hides the World
7.02.2014
Stars come out as evening twilight fades in this serene skyscape following the Persian proverb "Night hides the world, but reveals a universe." In the scene from last November, the Sun is setting over northern Kenya and the night will soon hide the shores of Lake Turkana, home to many Nile crocodiles.
The Terraced Night
6.02.2014
Long after sunset on January 25 an unusually intense red airglow floods this south-looking skyscape. The scene was recorded with a long exposure using a digital camera over Yunnan Province in southwest China. At best faintly visible to the eye, the lingering airglow is due to chemiluminescence, the production of light through chemical excitation.
NGC 2683: Edge On Spiral Galaxy
5.02.2014
Does spiral galaxy NGC 2683 have a bar across its center? Being so nearly like our own barred Milky Way Galaxy, one might guess it has. Being so nearly edge-on, however, it is hard to tell.
A Particle Beam Jet forms HH 24
4.02.2014
If you visit HH 24, don't go near the particle beam jet. This potential future travel advisory might be issued because the powerful jet likely contains electrons and protons moving hundreds of kilometers per second.
Lunar Time Lapse Panorama including Yutu Rover
3.02.2014
Where has the Yutu rover been on the Moon? Arriving in 2013 mid-December, the Chinese Yutu robotic rover has spent some of the past month and a half exploring Mare Imbrium on Earth's Moon. Because it uses solar power, the mechanical Jade Rabbit goes into sleep mode to endure the two-week long lunar night.
