“In addition to being an ellipse with a star at one focus, it also likely has a second inner disk that is misaligned or tilted relative to the outer disk.” “Until now, scientists had never seen a debris disk with such a complicated structure,” Dr. “But in elliptically-shaped eccentric disks, the star resides at one focus of the ellipse, far away from the disk’s center.”Īccording to the team, HD 53143 may also be harboring a second disk and at least one exoplanet. “In ring-shaped debris disks, the star is typically located at or near the center of the disk,” explained University of Colorado, Boulder astronomer Meredith MacGregor and her colleagues. The new observations from the Atacama Large Millimeter/submillimeter Array (ALMA) show that HD 53143’s debris disk is actually highly eccentric.
The star is surrounded by a debris disk that astronomers previously believed to be a face-on ring similar to the debris disk surrounding our Sun, more commonly known as the Kuiper Belt. HD 53143 was first observed in 2006 with the Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope. MacGregor, University of Colorado, Boulder / S. Image credit: ALMA / ESO / NAOJ / NRAO / M. Optical data from Hubble’s ACS camera is shown in blue and white a coronagraphic mask blocks out the starlight, allowing astronomers to see what’s happening in the region surrounding HD 53143. An unresolved dot shows the star off-center near the southern foci of the disk, while a second unresolved dot to the north indicates the potential presence of a planet. Shown in orange/red, millimeter-wavelength data from ALMA, reveal a previously unobserved eccentric debris disk orbiting HD 53143 in the form of an ellipse. DALL-E is really quite good at dressing up animals.This composite image shows the HD 53143 star system.
And while his face is indeed terrifying, it’s not much more terrifying than the actual Bonhomme.Īnd we end with this image of a polar bear in a skirt. This is what DALL-E returned for the prompt “Queen Victoria and the Bonhomme de Carnaval.” Note that the artificial intelligence was able to give Bonhomme an appropriately Victorian aesthetic. This is Levesque with some orcas, in other words. It is not known what Parti Québécois founder Rene Levesque thought of killer whales, but we can imagine a world in which his deep communion with the animals inspired him to attempt to found a Quebec nation that would embody their gentle strength. Given Trudeau’s penchant for dress-up, this is actually a pretty good guess. The instruction was only to render “Justin Trudeau and Elvis.” However, DALL-E unilaterally decided that if the prime minister were ever to meet the long-deceased King of Rock and Roll, he would apparently be wearing a matching rhinestone jumpsuit.
