Astronomy Picture Of the Day (APOD)
Unusual Dusty Galaxy NGC 7049
8.04.2009
How was this unusual looking galaxy created? No one is sure, especially since spiral galaxy NGC 7049 looks so strange. NGC 7049's strikingly appearance is primarily due to an unusually prominent dust ring seen mostly in silhouette. The opaque ring is much darker than the din of millions of bright stars glowing behind it.
APOD: 2009 April 7 The Colliding Spiral Galaxies of Arp 274
7.04.2009
Two galaxies are squaring off in Virgo and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. This is because galaxies are mostly empty space and, however bright, stars only take up only a small fraction of that space.
APOD: 2009 April 6 The International Space Station Expands Again
6.04.2009
The developing International Space Station (ISS) has changed its appearance again. In a recently completed mission, the Space Shuttle orbiter Discovery visited the ISS and added components that included a new truss and new solar panels.
Star Party on Planet Earth
4.04.2009
As twilight sweeps around planet Earth tonight (April 4), many amateur astronomers will set up their telescopes for a 24-hour global star party. The planetwide star party is part of 100 Hours of Astronomy (100HA), a project of the International Year of Astronomy 2009.
Around the World in 80 Telescopes
3.04.2009
Want to go on an extraordinary voyage? Today you can, by watching Around the World in 80 Telescopes. The 24-hour long webcast is organized by the European Southern Observatory for the International Year of Astronomy cornerstone project 100 Hours of Astronomy.
100 Hours of Astronomy Begins
2.04.2009
Today, 100 Hours of Astronomy begins, a cornerstone project of the International Year of Astronomy 2009 celebrating the 400th anniversary of Gallileo's original telescopic exploration of the sky. Running from April 2 through...
Astronauts Head Upgraded During Spacewalk
1.04.2009
First, a new truss was added. Then, new solar panels were installed. Now, as part of the planned upgrade of the International Space Station, an Expedition 18 astronaut has upgraded her own head.
In the Heart of the Tarantula Nebula
31.03.2009
In the heart of monstrous Tarantula Nebula lies huge bubbles of energetic gas, long filaments of dark dust, and unusually massive stars. In the center of this heart, is a knot of stars so dense that it was once thought to be a single star.
Possible Mud Volcanoes on Mars
30.03.2009
Is this a mud volcano on Mars? If so, could it be dredging up martian microbes? This strange possibility has been suggested recently and seems to fit several recent observations of Mars. First of all, hills like this seem to better resemble mud volcanoes on Earth than lava volcanoes and impact craters on Mars.
Signals of a Strange Universe
29.03.2009
Eleven years ago results were first presented indicating that most of the energy in our universe is not in stars or galaxies but is tied to space itself. In the language of cosmologists, a large cosmological constant is directly implied by new distant supernovae observations.
