A black hole is a place in space where gravity pulls so much that even light can't escape it. But what if another black hole tries to eat it? Would it destroy it or would they two simply merge into a larger black hole? Astronomers have previously detected a black hole devouring neutron stars in a single bite. Let's see what happens if there appears another black hole on the way...

Is there an alien civilization next door? It’s quite possible. Proxima Centauri b is in the habitable zone and is pretty similar in mass to the Earth.

The sun has a regular heartbeat, and we call it the solar cycle. But it's been a bit of a drama queen lately because it's experiencing a "solar minimum." Translation: fewer sunspots and less solar activity. Solar flares and sunspots usually spice things up, but they've been pretty scarce lately. Scientists have noticed that the Sun's magnetic field is getting all tangled up. This could mean some interesting magnetic storms on Earth, so keep an eye out for crazy auroras! Some folks are even suggesting this could be the start of a "Grand Solar Minimum" where the Sun chills out and we see cooler temperatures on Earth. So, keep those shades handy because the Sun's unpredictable behavior is making the space news headlines!

We've all been there – the heart-wrenching moment when your favorite snack takes a nosedive onto the floor. But wait up; science says you've got about a five-second grace period to scoop it up and declare it safe to munch, right? The whole "5-second rule" might not be legit science, but if it's a clean surface, and you're feeling brave, why not give it a go?

Let's imagine what it'd be like...

What SIM does stand for? It means subscriber identity module or subscriber identification module. The first SIM card in the world was developed in 1991 by the German company Giesecke & Devrient. They sold 300 SIM cards to Radiolinja, a Finnish wireless network operator. In 1992, they sold the first GSM mobile phone with a SIM card; it was a Nokia 1101. Today, it’s hard to find a person who’s never used a SIM card – over 7 billion gadgets around the world use them to make calls, send SMS and surf the web.
