Galileo had it coming





The Renaissance Mathematicus considers the importance that #Galileo's famously controversial work, Dialogo sopra i due massimi sistemi del mondo, actually played in the development of modern #astronomy:
What role did the #Dialogo actually play in the ongoing cosmological/astronomical debate in the seventeenth century? The real answer is, given its reputation, surprisingly little. In reality Galileo was totally out of step with the actual debate that was taking place around 1630. Driven by…

Astronomen haben mit dem Very Large Telescope der ESO Vorräte an kaltem Gas um einige der frühesten Galaxien des Universums herum beobachtet. Diese Gashalos sind die perfekte Nahrung für supermassereiche Schwarze Löcher im Zentrum dieser Galaxien, die heute so aussehen, wie sie vor über 12,5 Milliarden Jahren waren. Diese Reservoirs könnten erklären, wie diese kosmischen Giganten in einer Epoche des Universums, die als kosmische Morgendämmerung bekannt ist, so schnell wachsen konnten.

Successful launch from French Guiana of European project comes day late after glitch

Europe’s Cheops planet-hunting satellite has left Earth a day after its lift-off was delayed by a technical rocket glitch during the final countdown.

A 30cm telescope aboard has been designed to measure the density, composition, and size of numerous exoplanets, which orbit stars beyond our solar system.

Das Very Large Telescope (VLT) der ESO hat den zentralen Teil der Milchstraße mit spektakulärer Auflösung untersucht und neue Details über die Geschichte der Geburt von Sternen in unserer Galaxie aufgedeckt. Dank der neuen Beobachtungen haben die Astronomen Beweise für ein dramatisches Ereignis im Leben der Milchstraße gefunden: eine Epoche heftiger Sternenentstehung, die so intensiv war, dass sie zu über hunderttausend Supernova-Explosionen führte.

Astronomers find 19 more galaxies missing their dark matter

The new research may have dramatic implications for theories about both dark matter and galaxy formation.

Astronomers have discovered 19 more galaxies missing their dark matter. Instead of dark matter, these strange galaxies are mainly filled with regular matter, like the protons, neutrons, and electrons that make up everything we're familiar with.

The new find, published November 26 in Nature Astronomy, bolsters the controversial recent discovery of two other galaxies without dark matter. The mysterious substance accounts for most matter in the universe, and it's thought to be the primary component of all galaxies — as well as the main driver of galaxy formation in the first place. So, finding so many galaxies without the exotic matter suggests astronomers are missing something major about how galaxies form and evolve.

NASA's Treasure Map for Water Ice on Mars | NASA

NASA has big plans for returning astronauts to the Moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land?

A new paper published in Geophysical Research Letters will help by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface.

Is The Universe Finite? | PBS Space Time


Watch -- https://www.invidio.us/watch?v=F2s7vyKucis
Every time you walk out the door, light from the Big Bang strikes your face, enters your eyes. This is the cosmic microwave background radiation - the left-over heat-glow from the very early universe. We can’t see this microwave light with our eyes, but we can catch it with even a simple radio antenna. As soon as we became aware of its existence we’ve been feverishly building better and better devices to collect it. Why? Because it encodes so many secrets. And within this light, a group of scientists have just found evidence of the limits of space. A clue that our universe may be actually be finite in size. Today on Space Time Journal Club we’ll delve into the Nature Astronomy paper that just reported this: Planck evidence for a closed Universe and a possible crisis for cosmology by Eleonora Di Valentino,

Paleontology is AMAZING.

Look at this 18,000 year old dog.

Look at it. Seriously.

This is nuts. It looks like it is sleeping and could wake up any moment to beg for treats.

Scientists are trying to determine if it is a wolf or an early domesticated dog.

What If We Could Harness the Energy of a Black Hole?



What would happen if you put a couple of physicists in a room with a rope, a box and a black hole? They might come up with a plan to power the Earth for centuries. Black holes aren't something you come across every day.
To make a black hole of your own, you'd have to squeeze a star ten times bigger than our Sun into a sphere the diameter of New York City.
