The Blue Horsehead Nebula in Infrared

The Blue Horsehead Nebula looks quite different in infrared light. In visible light, the reflecting dust of the nebula appears blue and shaped like a horse’s head. In infrared light, however, a complex labyrinth of filaments, caverns, and cocoons of glowing dust and gas emerges, making it hard to even identify the equine icon. The featured image of the nebula was created in three infrared colors (R=22, G=12, B=4.6 microns) … Read More →

Meteor Over Crater Lake

Did you see it? One of the more common questions during a meteor shower occurs because the time it takes for a meteor to flash is typically less than the time it takes for a head to turn. Possibly, though, the glory of seeing bright meteors shoot across and knowing that they were once small granules on another world might make it all worthwhile, even if your observing partner(s) could … Read More →

TESS Launch Close Up

NASA’s Transiting Exoplanet Survey Satellite (TESS) began its search for planets orbiting other stars by leaving planet Earth on April 18. The exoplanet hunter rode to orbit on top of a Falcon 9 rocket. The Falcon 9 is so designated for its 9 Merlin first stage engines seen in this sound-activated camera close-up from Space Launch Complex 40 at Cape Canaveral Air Force Station. In the coming weeks, TESS will … Read More →

Moon in the Hyades

Have you seen the Moon lately? On April 18, its waxing sunlit crescent moved through planet Earth’s night across a background of stars in the Hyades. Anchored by bright star Aldebaran, the nearby, V-shaped star cluster and complete lunar orb appear in this telephoto image. The engaging skyview is actually digitally composed from a series of varying exposures. Recorded in 1/60th of a second, the shortest in the series captures … Read More →

NGC 7635: The Bubble Nebula

Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 7 light-year diameter bubble offers evidence of violent processes at work. Above and left of the Bubble’s center is a hot, O-type star, several hundred thousand times more luminous and some 45 times more massive than … Read More →

Milky Way over Deadvlei in Namibia

What planet is this? It is the only planet currently known to have trees. The trees in Deadvlei, though, have been dead for over 500 years. Located in Namib-Naukluft Park in Namibia (Earth), saplings grew after rainfall caused a local river to overflow, but died after sand dunes shifted to section off the river. High above and far in the distance, the band of our Milky Way Galaxy forms an … Read More →
