Astronomy Picture Of the Day (APOD)
Along the Taurus Molecular Cloud
22.11.2023
The cosmic brush of star formation composed this interstellar canvas of emission, dust, and dark nebulae. A 5 degree wide telescopic mosaic, it frames a region found north of bright star Aldebaran on the sky, at an inner wall of the local bubble along the Taurus molecular cloud.
IC 342: Hidden Galaxy in Camelopardalis
21.11.2023
Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise...
APOD: 2023 November 21 B Flemings Triangular Wisp
20.11.2023
These chaotic and tangled filaments of shocked, glowing gas are spread across planet Earth's sky toward the constellation of Cygnus as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star.
APOD: 2023 November 20 B The Horsehead Nebula
19.11.2023
Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable shape. Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex.
APOD: 2023 November 19 B Space Station, Solar Prominences, Sun
18.11.2023
That's no sunspot. It's the International Space Station (ISS) caught passing in front of the Sun. Sunspots, individually, have a dark central umbra, a lighter surrounding penumbra, and no Dragon capsules attached.
Planet Earth from Orion
17.11.2023
One year ago a Space Launch System rocket left planet Earth on November 16, 2022 at 1:47am EST carrying the Orion spacecraft on the Artemis I mission, the first integrated test of NASABs deep space exploration systems.
Nightlights in Qeqertaq
16.11.2023
Light pollution is usually not a problem in Qeqertaq. In western Greenland the remote coastal village boasted a population of 114 in 2020. Lights still shine in its dark skies though. During planet Earth's recent intense geomagnetic storm, on November 6 these beautiful curtains of aurora borealis fell over the arctic realm.
Daytime Moon Meets Morning Star
15.11.2023
Venus now appears as Earth's brilliant morning star, shining above the southeastern horizon before dawn. For early morning risers, the silvery celestial beacon rose predawn in a close pairing with a waning crescent Moon on Thursday, November 9.
M1: The Incredible Expanding Crab
14.11.2023
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: 2023 November 14 B Three Planets Rock
13.11.2023
In the fading darkness before dawn, a tilted triangle appeared to balance atop a rock formation off the southern tip of Sicily. Making up the points of the triangle are three of the four brightest objects visible in EarthBs sky: Jupiter, Venus and the Moon.
