APOD - NGC 6744 Close Up
Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Explanation: Beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo, its galactic disk tilted towards our line of sight. This Hubble close-up of the nearby island universe spans about 24,000 light-years across NGC 6744's central region in a detailed portrait that combines visible light and ultraviolet image data. The giant galaxy's yellowish core is dominated by the visible light from old, cool stars. Beyond the core are pinkish star forming regions and young star clusters scattered along the inner spiral arms. The young star clusters are bright at ultraviolet wavelengths, shown in blue and magenta hues.

APOD - The Case of the Backwards Orbiting Asteroid
Astronomy Picture of the Day

Explanation: Why does asteroid 2015 BZ509 orbit the Sun the backwards? As shown in the featured animation, Jupiter's trojan asteroids orbit the Sun in two major groups -- one just ahead of Jupiter, and one just behind -- but all orbit the Sun in the same direction as Jupiter. Asteroid BZ509 however, discovered in 2015 and currently unnamed, orbits the Sun in retrograde and in a more complex gravitational dance with Jupiter. The reason why is currently unknown and a topic of research -- but if resolved might tell us about the early Solar System. A recently popular hypothesis holds that BZ509 was captured by Jupiter from interstellar space billions of years ago, while a competing conjecture posits that BZ509 came from our Solar System's own distant Oort cloud of comets, perhaps more recently. The answer may only become known after more detailed models of the likelihood and stability of orbits near Jupiter are studied, or, possibly, by observing direct properties of the unusual object.

APOD - Aurora and Manicouagan Crater from the Space Station
Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Image Credit: NASA
Explanation: How many of these can you find in today's featured photograph: an aurora, airglow, one of the oldest impact craters on the Earth, snow and ice, stars, city lights, and part of the International Space Station? Most of these can be identified by their distinctive colors. The aurora here appears green at the bottom, red at the top, and is visible across the left of image. Airglow appears orange and can be seen hovering over the curve of the Earth. The circular Manicouagan Crater in Canada, about 100 kilometers across and 200 million years old, is visible toward the lower right and is covered in white snow and ice. Stars, light in color, dot the dark background of space. City lights appear a bright yellow and dot the landscape. Finally, across the top, part of the International Space Station (ISS) appears mostly tan. The featured image was taken from the ISS in 2012.
