Scientists have discovered the oldest black hole yet, a cosmic beast formed a mere 470 million years after the Big Bang. The findings, published Monday, confirm what until now were theories that supermassive black holes existed at the dawn of the universe. NASA’s James Webb Space Telescope and Chandra X-Ray Observatory teamed up over the past year to make the observations.

Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years.

A study from an international team led by researchers from Nagoya University in Japan and the University of New Hampshire in the United States has revealed the importance of the Earth’s upper atmosphere in determining how large geomagnetic storms develop. Their findings reveal the previously underestimated importance of the Earth’s atmosphere. Understanding the factors that cause geomagnetic storms is important because they can have a direct impact on the Earth’s magnetic field such as causing unwanted currents in the power grid and disrupting radio signals and GPS. This research may help predict the storms that will have the greatest consequences.

Scientists have long known that geomagnetic storms are associated with the activities of the Sun...

Using the James Webb Space Telescope, an international team, including astronomer Alexander de la Vega of the University of California, Riverside, has discovered the most distant barred spiral galaxy similar to the Milky Way that has been observed to date.

Until now it was believed that barred spiral galaxies like the Milky Way could not be observed before the universe, estimated to be 13.8 billion years old, reached half of its current age.

The research, published in Nature this week, was led by scientists at the Centro de Astrobiología in Spain.

“This galaxy, named ceers-2112, formed soon after the Big Bang,” said co-author de la Vega, a postdoctoral researcher in the Department of Physics and Astronomy...
