ALERT🚨: This equatorial coronal hole is now directly facing Earth! A stream of high-speed solar wind is expected to hit within 24 hours — and it could spark a geomagnetic storm.

• Location: ~5,000 light-years from Earth • Mass: ~7 times the Sun • Type: Stellar-mass black hole (not the supermassive one at our galaxy’s center) • Status: Drifting alone, with no companion star — a true “wanderer”

Using data from Hubble and Gaia, scientists spotted this cosmic ghost not by its light (it emits none) but through its gravitational lensing — its immense gravity bent and magnified the light of a distant star as it passed in front of it.

Thanks to radio waves penetrating cosmic dust blocking visible light, this image offers a unique view of the galactic core. Its creation required three years of analysis and combines 20 observations — equivalent to 200 hours of telescope use — covering six square degrees, about

Phenomena such as stellar explosions, regions where new stars are born and the turbulent area surrounding the black supermassive hole of the galactic center, with a mass of 4 million suns, located about 25 thousand light years from Earth are appreciated.

According to this study, the total lifetime of the universe could be about 33 billion years. The universe is about 13.8 billion years old today, which would leave roughly 20 billion years to go.

A new analysis suggests that story might be wrong. It argues that expansion could slow, stop, and – far in the future – reverse. This idea posits that the cosmological constant is actually negative, not positive, as we have assumed.
