Astronomy Picture Of the Day (APOD)
Messier 101
16.05.2025
Big, beautiful spiral galaxy M101 is one of the last entries in Charles Messier's famous catalog, but definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way.
A Plutonian Landscape
15.05.2025
This shadowy landscape of majestic mountains and icy plains stretches toward the horizon on a small, distant world. It was captured from a range of about 18,000 kilometers when New Horizons looked back toward Pluto, 15 minutes after the spacecraft's closest approach on July 14, 2015.
APOD: 2025 May 14 Б NGC 1360: The Robins Egg Nebula
14.05.2025
This pretty nebula lies some 1,500 light-years away, its shape and color in this telescopic view reminiscent of a robin's egg. The cosmic cloud spans about 3 light-years, nestled securely within the boundaries of the southern constellation of the Furnace (Fornax).
APOD: 2025 May 13 Б Gaia Reconstructs a Top View of our Galaxy
13.05.2025
What does our Milky Way Galaxy look like from the top? Because we are on the inside, humanity canБt get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESAБs Gaia mission.
APOD: 2025 May 12 Б Gaia Reconstructs a Side View of our Galaxy
12.05.2025
What does our Milky Way Galaxy look like from the side? Because we are on the inside, humanity canБt get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESAБs Gaia mission.
APOD: 2025 May 11 Б The Surface of Venus from Venera 14
11.05.2025
If you could stand on Venus -- what would you see? Pictured is the view from Venera 14, a robotic Soviet lander which parachuted and air-braked down through the thick Venusian atmosphere in March of 1982.
Yogi and Friends in 3D
10.05.2025
This picture from July 1997 shows a ramp from the Pathfinder lander, the Sojourner robot rover, deflated landing airbags, a couch, Barnacle Bill and Yogi Rock appear together in this 3D stereo view of the surface of Mars. Barnacle Bill is the rock just left of the house cat-sized, solar-paneled Sojourner.
APOD: 2025 May 9 Б IXPE Explores a Black Hole Jet
9.05.2025
How do black holes create X-rays? Answering this long-standing question was significantly advanced recently with data taken by NASAБs IXPE satellite. X-rays cannot exit a black hole, but they can be created in the energetic environment nearby, in particular by a jet of particles moving outward.
M1: The Incredible Expanding Crab
8.05.2025
Cataloged as M1, the Crab Nebula is the first on Charles Messier's famous list of things which are not comets. In fact, the Crab Nebula is now known to be a supernova remnant, an expanding cloud of debris from the death explosion of a massive star.
APOD: 2025 May 7 Б Galaxy Wars: M81 versus M82
7.05.2025
In the upper left corner, surrounded by blue arms and dotted with red nebulas, is spiral galaxy M81. In the lower right corner, marked by a light central line and surrounded by red glowing gas, is irregular galaxy M82.
