On April 30, 2024, the University of Tokyo Atacama Observatory (TAO) marked a significant milestone with its official opening. Researchers hope it will unravel some of the biggest mysteries, including how planets form, how galaxies evolve, and ultimately, how the universe itself began.

At an extraordinary height of 5,640 meters, TAO is now the highest astronomical observatory in the world. This exceptional altitude is expected to provide unparalleled observational capabilities, although it also presents unique challenges.

TAO is the highest astronomical observatory in the world, located at an altitude of 5,640 meters in the Atacama Desert in Chile.

Astronomers will go to ever greater lengths to get a better view of the universe. Going back hundreds of years, some of the first lenses were made for telescopes to bring the heavens closer to Earth. Since then, there have been optical telescopes with mirrors as big as buildings, radio telescopes with antennae that stretched between mountaintops, and there is even a space telescope, the James Webb Space Telescope, farther than the moon. And now, the University of Tokyo has opened another groundbreaking telescope, funded partly by the Japanese government.

The Atacama desert is known for its exceptionally clear skies, making it an ideal location for astronomical observation.

After 26 years of planning and construction, TAO is finally up and running. It is officially the highest observatory in the world and was awarded a Guinness World Record. Located in Chile's Atacama Desert, it's not far from another notable observatory frequently used by astronomers from Japanese institutions, the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope. But why does TAO have to be so high up and what benefits, and drawbacks, does that factor provide? .

The TAO project received funding from the Japanese government, as well as collaborations with local universities and Indigenous peoples.

"I'm seeking to elucidate mysteries of the universe, such as dark energy and primordial first stars. For this, you need to view the sky in a way that only TAO makes possible," said Emeritus Professor Yuzuru Yoshii, who has been leading the TAO project for 26 years as the principal investigator since 1998. "Of course, it contains state-of-the-art optics, sensors, electronics, and mechanisms, but the uniquely high altitude of 5,640 meters is what gives TAO such clarity of vision. At that height, there's little moisture in the atmosphere to impact its infrared sight.

The telescope at TAO is designed to observe the infrared spectrum, allowing for the study of dark energy and the first stars formed in the universe.

"Construction on the summit of Cerro Chajnantor was an incredible challenge, not just technically, but politically too. I have liaised with Indigenous peoples to ensure their rights and views are considered, the Chilean government to secure permission, local universities for technical collaboration, and even the Chilean Health Ministry to make sure people can work at that altitude in a safe manner. Thanks to all involved, research I've only ever dreamed about can soon become a reality, and I couldn't be happier." .

The construction of TAO was not only a technical challenge, but also required political negotiations with various stakeholders to ensure the safety and rights of all involved.

The incredible altitude of TAO makes it difficult and hazardous for humans to work there. The risk of altitude sickness is high, not only for construction work, but even for astronomers working there, especially at night when some symptoms can be worse. So, the question is, will all this effort and expense be worth it? What kinds of research will it offer the astronomical community, and by extension, human knowledge? .

The high altitude of TAO presents risks to human health, including altitude sickness, making it a difficult and hazardous place to work.

From dark energy to the formation of the first stars, TAO's powerful infrared telescope offers unprecedented opportunities for groundbreaking discoveries about the universe. The opening of TAO marks a new era in astronomical observation and human understanding of the cosmos.

With its official opening on April 30, 2024, the University of Tokyo Atacama Observatory (TAO) has become the highest astronomical observatory in the world, located at an altitude of 5,640 meters in the Atacama Desert in Chile.

New observations from the CHEOPS space telescope have revealed a mysterious "glory" in the atmosphere of WASP-76b, a highly unusual exoplanet. This "rainbow" phenomenon, caused by intense radiation from the planet's star, has been confirmed by detailed observations over a period of three years. If verified, this would be the first detection of a glory outside of our solar system and adds to the list of extreme and fascinating characteristics associated with WASP-76b.

Did Asteroids Cause 'Snowball Earth' Events?

Category Astronomy

tldr

A new study by a Yale-led research team suggests that 'Snowball Earth' events, in which the entire planet was covered in ice, may have been triggered by large asteroid impacts. Using a sophisticated climate model, the team found that in certain climate scenarios, an asteroid strike could have pushed Earth into a 'Snowball' state in just 10 years. This could explain the dramatic climate shifts that occurred during the Neoproterozoic era. The study challenges existing theories about declining greenhouse gases and offers a new perspective on past climate events on Earth.

Unlocking the Mystery of Hydrogen-Poor Supernovae

Astrophysicists have long been puzzled by the explanation of hydrogen-poor supernovae that seem to have materialized out of thin air. In order to better explain them, ISTA Assistant Professor Ylva Götberg and Maria Drout, an Associated Faculty Member of the Dunlap Institute for Astronomy & Astrophysics, University of Toronto, Canada, proposed an explanation which uncovers a first-of-its-kind star population which bridges the knowledge gap and may be the precursor star to the phenomenon. This population consists of stars interlocked in binary star systems, where the mass stripping of the more massive star by its companion eventually leaves a hot and compact helium core.
