The Great Cluster in the constellation Hercules – also known as Messier 13, or M13 – is considered to be the finest globular cluster in the northern half of the heavens. It’s found in a star pattern called the Keystone – a lopsided square within the constellation Hercules – between the two brightest stars of northern spring and summer, Vega and Arcturus.

When you gaze at M13 or other globulars, you are looking at stars that are thought to be 12 to 13 billion years old. That’s almost as old as the universe.

The Boomerang Nebula is a protoplanetary nebula located 5,000 light-years away from Earth in the constellation Centaurus. It is also known as the Bow Tie Nebula and catalogued as LEDA 3074547. The nebula's temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coolest natural place currently known in the Universe.

EXPLODING BINARY STARS WILL LIGHT UP THE SKY IN 2022

Premium Link Upgrade

Stellar collisions are an amazingly rare thing. According to our best estimates, such events only occur in our galaxy (within globular clusters) once every 10,000 years. It’s only been recently, thanks to ongoing improvements in instrumentation and technology, that astronomers have been able to observe such mergers taking place. As of yet, no one has ever witnessed this phenomena in action – but that may be about to change!

According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history. What’s more, they claim, this explosion will be visible with the naked-eye to observers here on Earth.

Man I hope they're right, because that would be awesome to see.

Nuclear pasta in neutron stars may be the strongest material in the universe.

Premium Link Upgrade

An exotic substance thought to exist within a type of collapsed star called a neutron star (illustrated) may be stronger than any other known material.

Predicted to exist in ultradense dead stars called neutron stars, nuclear pasta may be the strongest material in the universe. Breaking the stuff requires 10 billion times the ***** needed to crack steel, for example, researchers report in a study accepted in Physical Review Letters.

A disk of inflating supernova debris may be encircling a stellar corpse

Imagine crushing more than 50,000 aircraft carriers into the size of a baseball. This describes neutron stars. They are among the strangest objects in the universe. Neutron stars are a case of extreme physics produced by the unforgiving ***** of gravity. The entire core of an exploded star has been squeezed into a solid ball of neutrons with the density of an atom’s nucleus. Neutron stars spin as fast as a blender on puree. Some spit out death-star beams of intense radiation — like interstellar lighthouses. These are called pulsars.

"There are 4 bright planets in the evening sky now. This image from Yuri Beletsky in Chile's Atacama Desert shows them all. Venus is the brightest one, near the bottom of the image. Jupiter, Saturn and Mars extend upward in a line."
 
The Milky Way is Still Rippling from a Galactic Collision Millions of Years Ago

Premium Link Upgrade

Between 300 million and 900 million years ago, our Milky Way galaxy nearly collided with the Sagittarius dwarf galaxy. Data from the ESA’s Gaia mission shows the ongoing effect of this event, with stars moving like ripples on the surface of a pond. The galactic collision is part of an ongoing cannibalization of the dwarf galaxy by the much-larger Milky Way.

Man the Moon would've looked that big if you could go back a few hundred million years , or more. The tides would be massive though.

Astronomers spotted evidence of a neutron star’s birth after supernova 2012au exploded in the galaxy NGC 4790 (shown). The supernova was absent in a 2001 Hubble Space Telescope image of the galaxy (top panel), but visible as a bright dot in 2013 (bottom panel).

For the first time, astronomers may have watched a massive stellar explosion give rise in real time to a superdense dead star called a neutron star.
