Hubble sheds light on origins of supermassive Black Holes

April 18, 2022738 Views

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial "missing link" between young star-forming galaxies and the first supermassive black holes. They used data from NASA's Hubble Space Telescope to make this discovery. Until now, the monster, nicknamed GNz7q, had been lurking unnoticed in one of the best-studied areas of the night sky, the Great Observatories Origins Deep Survey-North (GOODS-North) field. Archival Hubble data from Hubble's Advanced Camera for Surveys helped the team determine that GNz7q existed just 750 million years after the big bang. The team obtained evidence that GNz7q is a newly formed black hole. Hubble found a compact source of ultraviolet (UV) and infrared light. This couldn't be caused by emission from ...

ESO telescope captures surprising changes in Neptune’s temperatures

An international team of astronomers have used ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track Neptune’s atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south pole. “This change was unexpected,” says Michael Roman, a postdoctoral research associate at the University of Leicester, UK, and lead author of the study published today in The Planetary Science Journal. “Since we have been observing Neptune during its early southern summer, we expected temperatures to be slowly growing warmer, not colder.” This composite shows thermal images of Neptune taken between 2006 and 2020. The first three images (2006, 2009, 2018) were t...

The first all-private team of astronauts ever launched to the International Space Station (ISS) were welcomed aboard the orbiting research platform on Saturday to begin a weeklong science mission hailed as a milestone in commercial spaceflight. Their arrival came about 21 hours after the four-man team representing Houston-based startup company Axiom Space Inc lifted off on Friday from NASA's Kennedy Space Center, riding atop a SpaceX-launched Falcon 9 rocket. The Crew Dragon capsule lofted into orbit by the rocket docked with the ISS at about 8:30 a.m. EDT (1230 GMT) on Saturday as the two space vehicles were flying roughly 250 miles (420 km) above the central Atlantic Ocean, a live webcast of the coupling from the National Aeronautics and Space Administration showed. The fin...

McDonald Observatory, Community Partners come together to form 15,000 sq miles reserve The world’s largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin’s McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others. The designation, granted by the IDA, recognizes the commitment of organizations, governments, businesses and residents in the region to maintaining dark skies. The move will benefit not only astronomical research, but also wildlife, ecology and tourism. The new Greater Big Bend International Dark Sky Reserve will encompass more than 15,000 square miles in portions of western Texas and northern Mexico. It is the only such reserve to cross an int...

Scientists have spotted the farthest Galaxy ever

Offers clues about the primordial universe An international team of astronomers, including researchers at the Center for Astrophysics | Harvard & Smithsonian, has spotted the most distant astronomical object ever: a galaxy. Named HD1, the galaxy candidate is some 13.5 billion light-years away and is described in the Astrophysical Journal. In an accompanying paper published in the Monthly Notices of the Royal Astronomical Society Letters, scientists have begun to speculate exactly what the galaxy is. The team proposes two ideas: HD1 may be forming stars at an astounding rate and is possibly even home to Population III stars, the universe’s very first stars — which, until now, have never been observed. Alternatively, HD1 may contain a supermassive black hole about 100 million t...

The International Space Station (ISS) is set to become busier than usual this week when its crew welcomes aboard four new colleagues from Houston-based startup Axiom Space, the first all-private astronaut team ever flown to the orbiting outpost. The launch is being hailed by the company, NASA and other industry players as a turning point in the latest expansion of commercial space ventures collectively referred to by insiders as the low-Earth orbit economy, or "LEO economy" for short.

Blue Origin makes 4th flight

Successfully lands after taking six on a 10-minute suborbital voyage Blue Origin, the space tourism venture launched by entrepreneur Jeff Bezos, completed its fourth flight with a crew on Thursday, landing successfully in rural west Texas after taking a half dozen passengers for a 10-minute suborbital joyride. The New Shepard spacecraft blasted off at 8:59 a.m. CDT (1359 GMT), and the crew capsule separated from the six-story-tall rocket a short time later as it soared to an altitude of 66 miles (106 km). University of North Carolina professor Jim Kitchen shows a flag with "194" written on it, symbolizing his visits to 193 countries on Earth and his trip to sub-orbital space, as he emerges from the capsule of Blue Origin's rocket New Shepard after landing near Van Horn, Texas, U....

Towering ice volcanoes identified on surprisingly vibrant Pluto

Could hint towards possibility of life on the dwarf planet A batch of dome-shaped ice volcanoes that look unlike anything else known in our solar system and may still be active have been identified on Pluto using data from NASA's New Horizons spacecraft, showing that this remote frigid world is more dynamic than previously known. Scientists said on Tuesday that these cryovolcanoes - numbering perhaps 10 or more - stand anywhere from six-tenths of a mile (1 km) to 4-1/2 miles (7 km) tall. Unlike Earth volcanoes that spew gases and molten rock, this dwarf planet's cryovolcanoes extrude large amounts of ice - apparently frozen water rather than some other frozen material - that may have the consistency of toothpaste, they said. A heart shaped region named Sputnik Planum is seen in a...

Delayed for two days because of poor weather conditions The fourth commercial flight of Jeff Bezos’ space tourism venture Blue Origin, offering short suborbital joyrides to well-heeled thrill-seekers and celebrity guests, has been delayed by two days because of poor weather conditions, the company said. Blue Origin’s New Shepard spacecraft was scheduled for liftoff on Tuesday from the company’s launch site in rural west Texas at 8:30 a.m. CDT (1330 GMT) with six would-be citizen astronauts strapped into the crew cabin atop the fully autonomous launch vehicle, standing nearly six stories tall.
