AR 3664 at the Sun’s Edge

By |2024-05-15T09:09:50-04:00May 15th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , |

Photo of the Day What did the monster active region that created the recent auroras look like when at the Sun's edge? There, AR 3664 better showed its 3D structure. Pictured, a large multi-pronged solar prominence was captured extending from chaotic sunspot region AR 3664 out into space, just one example of the particle [...]

AR 3664 on a Setting Sun

By |2024-05-13T09:09:10-04:00May 13th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , |

Photo of the Day It was larger than the Earth. It was so big you could actually see it on the Sun's surface without magnification. It contained powerful and tangled magnetic fields as well as numerous dark sunspots. Labelled AR 3664, it developed into one of the most energetic areas seen on the Sun [...]

Simulation: Two Black Holes Merge

By |2024-05-10T09:09:33-04:00May 10th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front [...]

The Galaxy, the Jet, and a Famous Black Hole

By |2024-05-09T09:09:42-04:00May 9th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is rendered in blue hues in this [...]

Visualization: A Black Hole Accretion Disk

By |2024-05-08T09:09:09-04:00May 8th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What would it look like to circle a black hole? If the black hole was surrounded by a swirling disk of glowing and accreting gas, then the great gravity of the black hole would deflect light emitted by the disk to make it look very unusual. The featured animated video [...]

Black Hole Accreting with Jet

Photo of the Day What happens when a black hole devours a star? Many details remain unknown, but observations are providing new clues. In 2014, a powerful explosion was recorded by the ground-based robotic telescopes of the All Sky Automated Survey for SuperNovae (Project ASAS-SN), with followed-up observations by instruments including NASA's Earth-orbiting Swift [...]

A Total Solar Eclipse from Sliver to Ring

By |2024-05-06T09:09:06-04:00May 6th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day This is how the Sun disappeared from the daytime sky last month. The featured time-lapse video was created from stills taken from Mountain View, Arkansas, USA on 2024 April 8. First, a small sliver of a normally spotted Sun went strangely dark. Within a few minutes, much of the background [...]

A Black Hole Disrupts a Passing Star

By |2024-05-05T09:09:09-04:00May 5th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day What happens to a star that goes near a black hole? If the star directly impacts a massive black hole, then the star falls in completely -- and everything vanishes. More likely, though, the star goes close enough to have the black hole's gravity pull away its outer layers, or [...]

Temperatures on Exoplanet WASP-43b

By |2024-05-03T09:09:18-04:00May 3rd, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day A mere 280 light-years from Earth, tidally locked, Jupiter-sized exoplanet WASP-43b orbits its parent star once every 0.8 Earth days. That puts it about 2 million kilometers (less than 1/25th the orbital distance of Mercury) from a small, cool sun. Still, on a dayside always facing its parent star, temperatures [...]

M100: A Grand Design Spiral Galaxy

By |2024-05-02T09:09:06-04:00May 2nd, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. The large galaxy of over 100 billion stars has well-defined spiral arms, similar to our own Milky Way. One of the brightest members of the Virgo Cluster of galaxies, M100, also known as NGC [...]
