☆ New 3D map reveals strange, glowing filaments surrounding a supernova
  + stars: | 2024-10-30 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +8 min
In this case, filaments radiate away from a “zombie star” the explosion created. Then, in 2023, astronomers spied weird filaments glowing with light from sulfur within the nebula. Scientists know the supernova created the filaments, but it’s unclear how or when the structures formed. The robust data that the instrument captured allowed the team to measure the motions of each filament and create a 3D map. The Keck Cosmic Web Imager enabled measurements of the velocity of any material within the nebula that emits light.

☆ Scientists surprised by source of largest quake detected on Mars
  + stars: | 2023-10-18 | by ( Will Dunham | ) www.reuters.com   time to read: +4 min
"We concluded that the largest marsquake seen by InSight was tectonic, not an impact. "Most of the marsquakes we've detected thus far have been associated with a region called Cerberus Fossae, located eastward of InSight. The energy it released surpassed the cumulative energy from all the other marsquakes InSight recorded. With future human missions to Mars in mind, a greater understanding of Martian seismic activity is pertinent. Charalambous said the location of the majority of the marsquakes detected by InSight remained uncertain, with a poor understanding of the mechanisms that triggered them.

☆ Webb telescope spies most distant supermassive black hole ever recorded
  + stars: | 2023-07-16 | by ( Jackie Wattles | ) edition.cnn.com   time to read: +4 min
CNN —The James Webb Space Telescope has delivered yet another astounding discovery, spying an active supermassive black hole deeper into the universe than has ever been recorded. And scientists were perplexed to find just how small the celestial object’s central black hole measures. “This black hole clocks in at about 9 million solar masses,” according to a NASA news release. Into the CEERS 1019 galaxyThe relative smallness of the black hole at CEER 1019’s center is a mystery for scientists. The astronomical community is already pouring over data that could pinpoint other, more distant black holes.

☆ The ‘Forbidden Planet’ That Escaped a Fiery Doom
  + stars: | 2023-06-28 | by ( Becky Ferreira | ) www.nytimes.com   time to read: +1 min
All across the Milky Way, dying stars are gobbling up their planets. Even Earth is likely to perish this way about five billion years from now, when the sun expands and devours its innermost worlds. But the giant planet Halla, which closely orbits a star 520 light years from Earth, appears to have narrowly escaped such an apocalyptic fate. Halla is “a forbidden planet of sorts,” said Marc Hon, a NASA Hubble fellow at the University of Hawaii at Manoa and an author of the study. In some systems, planets may even cannibalize each other, according to another recent study that found evidence of a gas giant that ate a Mercury-size world.

☆ Webb telescope takes striking image of planet Uranus
  + stars: | 2023-04-07 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +4 min
CNN —The James Webb Space Telescope has captured a new stunning image of ice giant Uranus, with almost all its faint dusty rings on display. Uranus has 13 known rings, with 11 of them visible in the new Webb image. A November Hubble image of Uranus (left) captured the planet's bright polar cap, while the recent Webb image displayed more detail, with a subtle enhanced brightness at the cap's center. With the exact mechanism behind the haze unknown, scientists are studying the polar cap using telescope images such as this new Webb image. In this new Webb image, similar to other recent images by the Hubble Space Telescope, storm clouds can be seen at the edge of the polar cap.
☆ NASA image may show first-ever 'rogue' supermassive black hole, leaving a trail of newborn stars in its wake
  + stars: | 2023-03-09 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com   time to read: +8 min
A NASA Hubble image may show the first runaway supermassive black hole ever discovered. Astrophysicists have long theorized that black holes could "go rogue" or "run away," if other black holes pushed them out of their galaxies. But nobody has ever confirmed a black hole wandering through intergalactic space, much less a supermassive black hole going rogue. And while two galaxies colliding is the simplest explanation for a rogue black hole, that's not what seems to have happened here. Even though they're invisible, there's no reason to worry about rogue supermassive black holes sneaking up on us from other galaxies.
