This week’s colorful image is from the new Vera C. Rubin Observatory in Chile. It is part of the initial images being released as the observatory comes online. This particular image was created by combining 678 separate images. It shows clouds of gas and dust that comprise the Trifid nebula (top of image) and the Lagoon nebula (middle of image).
The new observatory is funded by the U.S. National Science Foundation and the U.S. Department of Energy’s Office of Science, and is expected to operate for at least 10 years so it can provide more amazing images and information for astronomers. The timeline related to the creation of the observatory is provided below as well as via this link.
Dr. Vera C. Rubin was an American astronomer known for her work proving the existence “dark matter” in the Universe.
“Do not the James Webb images also fill us with wonder, and indeed a mysterious joy, as we contemplate their sublime beauty?…The authors of sacred Scripture, writing so many centuries ago, did not have the benefit of this privilege, yet their poetic and religious imagination pondered what the moment of creation must have been like.”

Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical. But during the pre-production of their new space show, “Encounters in the Milky Way,” they noticed a strange spiral pattern in the middle of the cloud. The show, which premiered on Monday at New York City’s Hayden Planetarium, featured a computer-generated visualisation of the Oort Cloud on the dome. The team was reviewing the animation when they noticed what appeared to be a spiral structure inside the typically spherical cloud shape.
The ‘city killer’ asteroid 2024 YR4 may not be on a collision course with Earth anymore. But NASA has raised the odds of it hitting the moon in just seven years’ time. According to the space agency, there’s now a 4.3 per cent chance that 2024 YR4 will smash into the moon on December 22, 2032…The impact event would be the first time scientists could watch a known asteroid create a lunar crater in real-time.
SpaceX’s Starlink satellites are leaking radio waves to such an extent that it could threaten our ability to study and understand the early universe, say astronomers. Interference from the thousands of Starlink satellites in orbit, where they provide a global internet service, has been a continuing concern for astronomers, who say that the radio emissions from the craft could affect sensitive telescopes that observe distant, and faint, radio sources. SpaceX has worked with astronomers to try to prevent this interference, by switching off their internet-transmitting beams when they fly over key telescopes, but it turns out that this isn’t enough.
Astronomers have detected a mystery stellar object that emitted pulses of light for two minutes every 44 minutes. A handful of objects like this have been found before, but this is the first to emit both radio waves and X-rays…An international team, led by Curtin University astronomer Ziteng Andy Wang, first detected a radio signal in data captured by CSIRO’s ASKAP radio telescope in Western Australia...By chance, the signal was also spotted by NASA’s Chandra X-ray Observatory on Valentine’s Day last year.
A team of astronomers believe they may have discovered a new dwarf planet—just like Pluto—on the edge of our solar system. The object—which orbits out beyond Neptune—has been named “2017 OF201” by the team, which was led by Sihao Cheng of the Institute for Advanced Study in Princeton, New Jersey. Cheng and colleagues estimate that the body has a diameter of more than 430 miles, which means that it may be large enough to qualify as a dwarf planet.
In a Universe that was only 700 million years old, long before Earth even formed, something unexpected happened. A massive galaxy stopped forming stars and went silent. This type of galaxy, called quiescent, typically needs billions of years to grow and then shut down star formation. But thanks to the powerful James Webb Space Telescope (JWST), astronomers have now confirmed that one such galaxy had already died young.This ancient galaxy, called RUBIES-UDS-QG-z7, is now the most distant quiescent galaxy ever confirmed. It challenges current ideas about how quickly galaxies form and evolve in the early Universe. This discovery pushes the boundaries of what scientists thought was possible during cosmic dawn.

This week’s image comes from the National Science Foundation’s (NSF) Daniel K. Inouye Solar Telescope. Using a newly developed Visible Tunable Filter, it is able to produce detailed images of the Sun’s surface.
Carrie Black, NSF program director for the NSF National Solar Observatory, stated:
When powerful solar storms hit Earth, they impact critical infrastructure across the globe and in space. High-resolution observations of the sun are necessary to improve predictions of such damaging storms…The NSF Inouye Solar Telescope puts the U.S. at the forefront of worldwide efforts to produce high-resolution solar observations and the Visible Tunable Filter will complete its initial arsenal of scientific instruments.
