What Happens to a Planet That Gets Too Close to a Black Hole?
Contrary to a common belief that black holes work like cosmic vacuum cleaners pulling everything into their depths, the reality is considerably more nuanced and, in many ways...

Did you know the sunlight warming your face right now is older than the pyramids, older than agriculture, older than modern humans themselves?

Many people picture a black hole as a cosmic vacuum cleaner: the moment one shows up nearby, Earth is doomed, since its gravity is supposedly so monstrous that resisting the pull is futile at any distance. In reality, a black hole has no special "sucking force":
This is one of the most astonishing photos NASA has ever taken. The object in this image looks like a ghost, but it is actually a photograph of the coldest place in the Universe, with a temperature of about -272°C.

The Andromeda Galaxy (Messier 31, NGC 224) is the largest structure in our cosmic neighborhood, spanning 220,000 light-years in diameter - more than twice the width of the Milky Way.

Look at this object discovered by NASA's James Webb Space Telescope (@NASAWebb ), imaged by the Mirage or Miracle survey team - a completely new type of cosmic object never encountered by humanity before.

Look at this photo, it's not an AI image but a real NASA capture taken on March 5 and 6, 2026 by the Landsat 8 and Landsat 9 satellites. What you're seeing isn't Mars, as some might have thought, but our own planet Earth.

We know of more than 3500 nebulae, that's all our telescopes have managed to spot so far. But their real number is likely at least 20 000, the rest are hidden behind thick clouds of cosmic dust.

Of all the objects the James Webb Telescope has turned to so far, few rival the sheer beauty of the Lion Nebula (NGC 2392) - a glowing, jewel-like shell suspended in the constellation Gemini, about 6500 light-years from Earth.

This is a real photo of Betelgeuse, captured with @almaobs - the radio telescope array in Chile jointly operated by @ESO , @TheNRAO and the National Astronomical Observatory of Japan.

If we imagine time not as a line, but as a space, our lives might look completely different. We would exist simultaneously in all the moments we have ever lived through, simply without being able to see them all at once.

Supermassive Black Hole Gravitational Lensing and Golden Halo.
Einstein predicted this in his equations a hundred years ago. We have only now learned to visualize it.

Comet's tail isn't a wake trailing behind it. It always points away from the Sun, whatever direction the comet is moving. On the outbound leg, comets fly tail-first. Solar wind and sunlight sweep evaporating gas and dust outward, shaping the tail.
