The first test image from the groundbreaking observatory named after pioneering astronomer Bella Rubin captured light from millions of distant stars and galaxies on an unprecedented scale – And it is expected to reveal thousands of asteroids that were previously invisible.
The National Science Foundation has released only a few images so far and a brief video clip of the first image from Vera C. Rubin Observatory, but the images and videos taken using the largest camera ever built will be shared on the agency’s YouTube channel at 11:30am on Monday. The facility is jointly funded by the National Science Foundation and the Department of Energy’s Science Bureau.
The new image represents over 10 hours of test observations, providing a quick preview of the observatory’s decade-long mission, exploring the mysteries of the universe like never before.
“The NSF-Doe Rubin Observatory acquires more information on space throughout history than all optical telescopes,” said Brian Stone, Chief of Staff of the National Science Foundation, who currently performs the duties of NSF Director (as it is currently open).
Among the first results of the observation deck was the discovery of 2,104 asteroids, including seven near Earth asteroids that have never been seen in the solar system. Observatory scientists say none of the newly discovered nearby asteroids pose a risk to our planet. Images of the asteroid are expected to be shared later on Monday.
According to the National Science Foundation, terrestrial and space-based telescopes discover around 20,000 asteroids each year, but are expected to discover millions of space rocks within the first two years. Telescopes are also considered the most effective way to find interstellar comets and asteroids that could pass through our solar system.
Observatory mirror design, sensitive cameras, telescope speeds are all the first of its kind, allowing Rubin to find small faint objects such as asteroids. The observation deck also constantly captures thousands of images each night, cataloging changes in brightness, revealing hidden space rocks like nearby asteroids that could be on the collision course with our planet, according to the foundation.
Sneak Peak, shared Monday, contains videos made from over 1,100 images taken by the observatory, starting with a detailed look at the two galaxies. The video then zooms out and shows around 10 million galaxies discovered in the wide views of the camera. Rubin is about 0.05% of the 200 billion galaxies observed over a decade.
The observation deck team has also released a mosaic of the Nebulae of Trifid and Lagoon, a cloud-like star-forming region in the Sagittarius constellation. The mosaic, which consisted of 678 separate images, photographed over just seven hours, captured faint details, including nebulae and dust clouds thousands of years from Earth.
The first image was chosen to showcase the huge field of view of the telescope. This gives you a detailed glimpse into interacting galaxies and allows for a broader view of millions of galaxies.
“It has a very broad view and rapid cadence, so you have that moving aspect of the night sky,” said Dr. Sandrine Thomas, Telescope Project Scientist at Rubin Observatory.
The observatory in the Andes, located on the top of Cerro Pachong in Chile, is almost complete after about 20 years of work. The facility is set to achieve “first light” on July 4th using the 8.4 metres (27.5 feet) Simonyi Survey Telescope or make the first scientific observation of the southern hemisphere sky.
The central Chilean region is also home to other ground observatory observatory, and is preferred for astronomical observation because it provides dry air and dark skies.
The observatory’s main purpose is a super-advanced, ultra-high resolution film of space, created by scanning the entire sky for over a decade, cries, stars, exploding the stars, and captures time-lapse editing of distant galaxies. The investigation is expected to begin 4-7 months after the initial light.
“(Rubin) allows galaxies, milky stars, objects in the solar system, and everything to be explored in a truly new way. It captures images of the night sky so quickly and frequently, detecting millions of changing objects every night.
Rudman was responsible for assembling and testing the Rubin Observatory’s camera.
Rubin’s ability to find interesting phenomena allows it to become a “discovery machine” that can identify interesting areas of focus on other telescopes, Rudman said. Observatory can also allow detection of previously unknown types of celestial objects.
The same name of the telescope, considered to be one of the most influential female astronomers, provided some of the first evidence that dark matter existed. To Rubin’s honor, the telescope is expected to continue her pioneering work.
“Through this incredible scientific facility, we explore many universe mysteries, including dark matter and dark energy that permeates the universe,” Stone said.
According to NASA, dark matter is the mysterious material that shapes the universe, and dark energy is the force that accelerates the expansion rate of the universe. They are thought to make up most of the universe, but neither is possible to directly observe, but can be detected due to the gravity effect.
“Rubin has great potential to help us learn what dark energy is and how the universe is accelerating here,” Rudman said. “Looking at Rubin’s billions of galaxies, his unique ability to represent images repeatedly over the decade, will literally allow him to see the universe in a new way.”
