Moon and Venus Appulse over a Tree

What’s that bright spot near the Moon? Venus. About a week ago, Earth’s Moon appeared unusually close to the distant planet Venus, an angular coincidence known as an appulse. Similar to a conjunction, which is a coordinate term, an appulse refers more generally to when two celestial objects appear close together. This Moon and Venus appulse — once as close as 0.05 degrees — was captured rising during the early … Read More →

Perijove 16: Passing Jupiter

Watch Juno zoom past Jupiter again. NASA‘s robotic spacecraft Juno is continuing on its 53-day, highly-elongated orbits around our Solar System’s largest planet. The featured video is from perijove 16, the sixteenth time that Juno has passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter’s cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in … Read More →

Henize 70: A Superbubble in the LMC

Massive stars profoundly affect their galactic environments. Churning and mixing interstellar clouds of gas and dust, stars — most notably those upwards of tens of times the mass of our Sun — leave their mark on the compositions and locations of future generations of stars. Dramatic evidence of this is illustrated in our neighboring galaxy, the Large Magellanic Cloud (LMC), by the featured nebula, Henize 70 (also known as N70 … Read More →

An Airglow Fan from Lake to Sky

Why would the sky look like a giant fan? Airglow. The featured intermittent green glow appeared to rise from a lake through the arch of our Milky Way Galaxy, as captured during 2015 next to Bryce Canyon in Utah, USA. The unusual pattern was created by atmospheric gravity waves, ripples of alternating air pressure that can grow with height as the air thins, in this case about 90 kilometers up. … Read More →
