The Light, Dark, and Dusty Trifid

By |2024-08-10T09:09:22-04:00August 10th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Messier 20, popularly known as the Trifid Nebula, lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection [...]

Milky Way Behind Three Merlons

By |2024-08-07T09:09:10-04:00August 7th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day To some, they look like battlements, here protecting us against the center of the Milky Way. The Three Merlons, also called the Three Peaks of Lavaredo, stand tall today because they are made of dense dolomite rock which has better resisted erosion than surrounding softer rock. They formed about 250 [...]

Gaia: Here Comes the Sun

By |2024-08-04T09:09:06-04:00August 4th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , |

Photo of the Day What would it look like to return home from outside our galaxy? Although designed to answer greater questions, data from ESA's robotic Gaia mission is helping to provide a uniquely modern perspective on humanity's place in the universe. Gaia orbits the Sun near the Earth and resolves stars' positions so [...]

Comet Olbers over Kunetice Castle

Photo of the Day A visitor to the inner solar system every 70 years or so Comet 13P/Olbers reached its most recent perihelion, or closest approach to the Sun, on June 30 2024. Now on a return voyage to the distant Oort cloud the Halley-type comet is recorded here sweeping through northern summer night [...]

Leopard Spots on Martian Rocks

By |2024-07-31T09:09:08-04:00July 31st, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What is creating these unusual spots? Light-colored spots on Martian rocks, each surrounded by a dark border, were discovered earlier this month by NASA's Perseverance Rover currently exploring Mars. Dubbed leopard spots because of their seemingly similarity to markings on famous Earth-bound predators, these curious patterns are being studied with [...]

Arp 142: Interacting Galaxies from Webb

By |2024-07-30T09:09:25-04:00July 30th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day To some, it looks like a penguin. But to people who study the universe, it is an interesting example of two big galaxies interacting. Just a few hundred million years ago, the upper NGC 2936 was likely a normal spiral galaxy: spinning, creating stars, and minding its own business. Then [...]

Saturn at the Moon’s Edge

By |2024-07-27T09:09:06-04:00July 27th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Saturn now rises before midnight in planet Earth's sky. On July 24, the naked-eye planet was in close conjunction, close on the sky, to a waning gibbous Moon. But from some locations on planet Earth the ringed gas giant was occulted, disappearing behind the Moon for about an hour from [...]

The Crab Nebula from Visible to X-Ray

By |2024-07-23T09:09:08-04:00July 23rd, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What powers the Crab Nebula? A city-sized magnetized neutron star spinning around 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core. About 10 light-years across, the spectacular picture of the Crab Nebula (M1) frames [...]

King of Wings Hoodoo under the Milky Way

By |2024-07-21T09:09:15-04:00July 21st, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day This rock structure is not only surreal -- it's real. Perhaps the reason it's not more famous is that it is smaller than one might guess: the capstone rock overhangs only a few meters. Even so, the King of Wings outcrop, located in New Mexico, USA, is a fascinating example [...]

Anticrepuscular Rays at the Planet Festival

By |2024-07-19T09:09:12-04:00July 19th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day For some, these subtle bands of light and shadow stretched across the sky as the Sun set on July 11. Known as anticrepuscular rays, the bands are formed as a large cloud bank near the western horizon cast long shadows through the atmosphere at sunset. Due to the camera's perspective, [...]
