NASA Astronomy Picture of the Day:

Rising over a frozen valley in the Tatra Mountains, the familiar stars and nebulas of Orion dominate this wide-field nightscape. The featured deep photo was taken in southern Poland's highest mountain range last month, where dark skies and alpine terrain combined to reveal both Earth's rugged beauty and the structure of our galaxy. Above the snowy mountains, Orion's bright belt stars anchor a region of glowing interstellar clouds. The Great Orion Nebula, a vast stellar nursery visible even to the unaided eye, shines near the center of the scene. Surrounding it is the enormous arc of Barnard's Loop, a faint shell of ionized hydrogen gas spanning much of the constellation. To the left, the round Rosette Nebula glows softly, while the grayish Witch Head Nebula hovers to the right, illuminated by nearby starlight. Near the top, the orange supergiant Betelgeuse marks the hunter's shoulder.

“Selection” of Hungarian Jews on the ramp at Auschwitz-II-Birkenau in German-occupied Poland, May/June 1944, during the final phase of the Holocaust. Jews were sent either to forced labor or the gas chambers. 81 years ago today, on January 27, 1945, Auschwitz was liberated by the Red Army. Today is also International Holocaust Remembrance Day.

NASA Astronomy Picture of the Day:

Can you see nebulas in other galaxies? Yes, some nebulas shine brightly enough -- if you know how to look. Clouds of hydrogen and oxygen emit light at very specific colors, and by isolating them, astronomers and astrophotographers can reveal structures that would otherwise be too faint to notice. This deep, 50-hour exposure highlights glowing hydrogen (red) and oxygen (blue) across galaxy NGC 55, viewed nearly edge-on. Also known as the String of Pearls Galaxy, NGC 55 is often compared to our Milky Way's satellite galaxy the Large Magellanic Cloud (LMC), although NGC 55 lies much farther away at about 6.5 million light-years. The resulting image uncovers a sprinkling of emission nebulas within and sometimes above the galaxy's dusty disk, offering a detailed look at distant star-forming regions.

Apple orchards after snowfall in Sangla in the northern Indian state of Himachal Pradesh. India has the second largest area under apple cultivation in the world and is the fifth largest producer of the fruit globally. More than 90% of India's apple production comes from just two of its northern Himalayan states: Jammu and Kashmir, and Himachal Pradesh. Today is Republic Day in India.

NASA Astronomy Picture of the Day:

This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic. These Martian moons may well be captured asteroids originating in the main asteroid belt between Mars and Jupiter or perhaps from even more distant reaches of our Solar System. The larger moon, Phobos, is indeed seen to be a cratered, asteroid-like object in this stunning color image from the robotic Mars Reconnaissance Orbiter, which can image objects as small as 10 meters. But Phobos orbits so close to Mars - about 5,800 kilometers above the surface compared to 400,000 kilometers for our Moon - that gravitational tidal forces are dragging it down. In perhaps 50 million years, Phobos is expected to disintegrate into a ring of debris.
