Earth possibly exposed to interstellar anomaly millions of years ago

Scientists search the earth and sky for clues to the climate history of our planet. Powerful and persistent volcanic eruptions can change the climate over long periods of time, and the sun’s output can change Earth’s climate over millions of years. But what about interstellar hydrogen clouds? Could these gas and dust regions change Earth’s … Read more

12 billion years of black hole history revealed by X-rays and simulations

A spacey expanse that fades from starry black on the left to gaseous blue on the right half. A white square captures a small purple star on the left. White lines extend from the bottom corners to an image in the bottom left of yellow and red gas circling a black spot that shoots white light up and down.

The history of the black hearts of galaxies is almost completely told for the first time, when astronomers combined X-ray observations with detailed supercomputer models to record the growth of galaxies. supermassive black holes more than 12 billion years of cosmic history. The scientists have shown that the black hole forms the core of our … Read more

Two million years ago, an encounter between the sun and something outside the solar system changed all life on Earth

New research from Boston University and the Harvard Radcliffe Institute suggests that the sun passed through a massive hydrogen cloud two million years ago, directly impacting the protective heliosphere and possibly permanently altering all life on Earth. Evidence for this event and its effects on Earth’s climate also shows that the Sun’s location in the … Read more
