Fox Fur, Cone, and Christmas Tree

By |2024-12-24T08:09:06-05:00December 24th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , |

Photo of the Day What do the following things have in common: a cone, the fur of a fox, and a Christmas tree? Answer: they all occur in the constellation of the Unicorn (Monoceros). Considered as a star forming region and cataloged as NGC 2264, the complex jumble of cosmic gas and dust is [...]

Near to the Heart Nebula

By |2024-12-17T08:09:16-05:00December 17th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What excites the Heart Nebula? First, the large emission nebula on the upper left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by sulfur [...]

A Kilometer High Cliff on Comet Churyumov – Gerasimenko

By |2024-12-16T08:09:08-05:00December 16th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day This kilometer high cliff occurs on the surface of a comet. It was discovered on the dark nucleus of Comet Churyumov - Gerasimenko (CG) by Rosetta, a robotic spacecraft launched by ESA, which orbited the comet from 2014 to 2016. The ragged cliff, as featured here, was imaged by Rosetta [...]

Geminid Meteors over a Snowy Forest

By |2024-12-15T08:09:06-05:00December 15th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Meteors have been flowing out from the constellation Gemini. This was expected, as mid-December is the time of the Geminid Meteor Shower. Pictured here, over two dozen meteors were caught in successively added exposures taken over several hours early Saturday morning from a snowy forest in Poland. The fleeting streaks [...]

M51: Tidal Streams and H-alpha Cliffs

By |2024-12-13T08:09:06-05:00December 13th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day An intriguing pair of interacting galaxies, M51 is the 51st entry in Charles Messier's famous catalog. Perhaps the original spiral nebula, the large galaxy with whirlpool-like spiral structure seen nearly face-on is also cataloged as NGC 5194. Its spiral arms and dust lanes sweep in front of its smaller companion [...]

The Shells and Jets of Galaxy Centaurus A

By |2024-12-11T08:09:07-05:00December 11th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What's the closest active galaxy to planet Earth? That would be Centaurus A, cataloged as NGC 5128, which is only 12 million light-years distant. Forged in a collision of two otherwise normal galaxies, Centaurus A shows several distinctive features including a dark dust lane across its center, outer shells of [...]

The Great Meteor Storm of 1833

By |2024-12-10T08:09:08-05:00December 10th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day It was a night of 100,000 meteors. The Great Meteor Storm of 1833 was perhaps the most impressive meteor event in recent history. Best visible over eastern North America during the pre-dawn hours of November 13, many people -- including a young Abraham Lincoln -- were woken up to see [...]

Pleiades: The Seven Sisters Star Cluster

By |2024-12-09T08:09:09-05:00December 9th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as large and clear as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen with the unaided eye even from the depths [...]

Aurora around Saturn’s North Pole

By |2024-12-08T08:09:08-05:00December 8th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Are Saturn's auroras like Earth's? To help answer this question, the Hubble Space Telescope and the Cassini spacecraft monitored Saturn's North Pole simultaneously during Cassini's final orbits around the gas giant in September 2017. During this time, Saturn's tilt caused its North Pole to be clearly visible from Earth. The [...]

Xuyi Station and the Fireball

By |2024-12-06T08:09:08-05:00December 6th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Colorful and bright, this streaking fireball meteor was captured in a single exposure taken at Purple Mountain (Tsuchinshan) Observatory’s Xuyi Station in 2020, during planet Earth's annual Perseid meteor shower. The dome in the foreground houses the China Near Earth Object Survey Telescope (CNEOST), the largest multi-purpose Schmidt telescope in [...]
