The Helix Nebula from CFHT

Will our Sun look like this one day? The Helix Nebula is one of brightest and closest examples of a planetary nebula, a gas cloud created at the end of the life of a Sun-like star. The outer gasses of the star expelled into space appear from our vantage point as if we are looking down a helix. The remnant central stellar core, destined to become a white dwarf star, … Read More →

A Jupiter Vista from Juno

Why do colorful cloud bands encircle Jupiter? Jupiter‘s top atmospheric layer is divided into light zones and dark belts that go all the way around the giant planet. It is high horizontal winds — in excess of 300 kilometers per hour — that cause the zones to spread out planet-wide. What causes these strong winds remains a topic of research. Replenished by upwelling gas, zonal bands are thought to include … Read More →

Dark Molecular Cloud Barnard 68

Where did all the stars go? What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud. Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help make the interiors of molecular clouds some of the coldest and most isolated places in the universe. One of the … Read More →

Mars and Meteor over Jade Dragon Snow Mountain

A brilliant yellowish celestial beacon, Mars still dazzles in the night. Peering between clouds the wandering planet was briefly joined by the flash of a meteor in this moonless dark sky on November 18. The single exposure was taken as the Earth swept up dust from periodic comet Tempel-Tuttle during the annual Leonid Meteor Shower. The view of a rugged western horizon looks along the Yulong mountain range in Yunnan … Read More →

Global Map: Mars at Opposition

This may be the best global Mars map made with a telescope based on planet Earth. The image data were captured by a team of observers over six long nights at the Pic du Midi mountaintop observatory between October 8 and November 1, when the fourth rock from the Sun had not wandered far from its 2020 opposition and its biggest and brightest appearance in Earth’s night sky. The large … Read More →

Crew 1 Mission Launch Streak

Leaving planet Earth for a moment, a SpaceX Falcon 9 rocket arced into the early evening sky last Sunday at 7:27 pm EST. This 3 minute 20 second exposure traces the launch streak over Kennedy Space Center’s Launch Complex 39A. The rocket carried four astronauts en route to the International Space Station on the first flight of a NASA-certified commercial human spacecraft system. Dubbed Resilience, the astronauts’ Crew Dragon spacecraft … Read More →
