New telescope data has revealed that a dwarf planet in the outer reaches of the solar system has a dense ring around it, leaving scientists and astronomers confused as to why.
Scientists at the European Space Agency announced Wednesday that data and observations of the planet Quaoar which was collected between 2018 and 2021 —from ground-based telescopes, and the space-based telescope Cheops — led them to the discovery.
The ESA disclosed that Quaoar crossed in front of a succession of distant stars, blocking their light as it passed, in an event called an occultation. When the planet blocked that light, scientists were able to see its ring.

The United States launched military strikes on three Iranian nuclear facilities Sunday morning local time, an action President Trump said aimed to neutralize a threat "posed by the world's number one state sponsor of terror." It was widely seen as a turning point in America's involvement in the ongoing Middle East conflicts as the first direct intervention by U.S. forces in the war between Israel and Iran.

Erbil, Iraq — Israel has been hammering Iran's nuclear and military sites for a week. To reach their targets, Israeli warplanes must cover about 1,000 miles, traversing as many as three countries, including Iraq, which sits right on Iran's western border. For decades, Iranian groups opposed to the Islamic Republic's theocratic rulers have organized in exile across the border in Iraq, including ethnic Kurdish factions that have become well organized, and armed.
