Many of these smaller worlds are shrouded in haze, but this one seems to have clear skies and to be unusually hot.

TOI-421 B sits several times closer to its star than earth does to the sun. The planet’s atmosphere reaches around 1,340°F, which is intense even by exoplanet standards.

Astronomers using the Webb Telescope used a method known as transmission spectroscopy to spot water in the planet’s upper layers.

The universe is a complete unknown to humans. We are not yet able to control and understand the system in which Earth is located, as evidenced by the possible discovery made by a group of astronomers from the University of Taiwan, who suggest that they may have found clues to the existence of a ninth planet.

The Solar System is currently known to be made up of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, apart from Pluto, which has long been considered a dwarf planet. But one more could join this select group, according to an infrared study carried out between 1986 and 2006.

The work was based on data from the Infrared Astronomical Satellite (IRAS) and the Japanese satellite AKARI, which detected an object moving between 46.5 billion and 65.1 billion miles from the Sun, meaning it would take between 10,000 and 20,000 years to complete an orbit.

As part of the Chicago-Carnegie Hubble Program, astronomers using the NASA/ESA/CSA James Webb Space Telescope have performed new measurements of the Hubble constant.

Can we build an ecosystem on Mars — and should we?

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it. The discovery could further challenge theories of planet formation.

In the intriguing realm of star-forming galaxies, the key factor isn’t the total amount of gas but rather its strategic distribution within the galaxy.

Researchers at the International Centre for Radio Astronomy Research (ICRAR) made the discovery about galaxies by studying the gas distribution that helps create stars.

Using CSIRO’s ASKAP radio telescope located at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, researchers explored the gas distribution in about 1,000 galaxies as part of the WALLABY survey.

In the name of open science, the multinational scientific collaboration COSMOS on Thursday released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, built with data collected by the James Webb Space Telescope (JWST), consists of all the imaging and a catalog of nearly 800,000 galaxies spanning nearly all of cosmic time. And it’s been challenging existing notions of the infant universe.

“Our goal was to construct this deep field of space on a physical scale that far exceeded anything that had been done before,” said UC Santa Barbara physics professor Caitlin Casey, who co-leads the COSMOS-Web collaboration alongside Jeyhan Kartaltepe of the Rochester Institute of Technology.

“If you had a printout of the Hubble Ultra Deep Field on a standard piece of paper,” she said, referring to the iconic view of nearly 10,000 galaxies released by NASA in 2004, “our image would be slightly larger than a 13-foot by 13-foot-wide mural, at the same depth. So it’s really strikingly large.”
