Artist’s concept of a sun-like star (left) and a rocky planet about 60% larger than Earth in orbit in the star’s habitable zone. Gravitational microlensing has the ability to detect such planetary systems and determine the masses and orbital distances, even though the planet itself is too dim to be seen.

But here's the thing -- it only appears when you're running an app that you make calls with, such as the Phone app, Zoom, or WhatsApp. With that app running, access the Control Center, and you'll see Mic Mode.

Chinese scientists discovered a primitive forest in a giant sinkhole earlier this month. The sinkhole is 630 feet deep, and a team of spelunkers rappelled down into it in early May. While exploring, they found three separate cave entrances and a growing forest. Thankfully, the unique environment has been captured on video.

Black holes are thought to reside at the centre of most galaxies, including our Milky Way, holding important clues to the functioning of these giants. A group of researchers has now found a previously overlooked trove of massive black holes in dwarf galaxies. Black holes are usually detected when they actively grow by consuming gas around them, which makes them glow intensely. These black holes, the researchers believe, can offer insights into the journey of the supermassive black hole that sits at the centre of the Milky…
