PBS: Space Time | Strange Stars

What happens when matter can’t get any denser yet somehow does? The answer – it becomes “strange.” Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes. Neutron stars are made of a substance known as Neutronium. It …

TED: The most mysterious star in the universe | Tabetha Boyajian

Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea …

Harvard University: Cara Battersby: The Wild West of Star Formation

We saddle up to explore the extreme center of our Milky Way galaxy – one of the wildest sections of the outer-space frontier. Our Galactic center is a chaotic region containing dense gas, stars, and the biggest bully around these parts: a supermassive black hole. The normal rules for star formation don’t apply here, and …

NASA’s Ames Research Center: Caught for the First Time: The Early Flash of an Exploding Star

The brilliant flash of an exploding star’s shockwave—what astronomers call the “shock breakout” — is illustrated in this cartoon animation. The animation begins with a view of a red supergiant star that is 500 times bigger and 20,000 brighter than our sun. When the star’s internal furnace can no longer sustain nuclear fusion its core …

Times Infinity: Size comparison of the universe

From the quantum size to the cosmic scale, the size comparison of the entire universe will show you how large things really are! This is an update to my previous size comparison video published on the same date in 2013.  

NASA: Massive Black Hole Shreds Passing Star

NASA has released an animation of how it looks when a star gets too close to a black hole and what happens then. This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In …

ESO: Artist’s impression of the hottest and most massive touching double star

This animated artist’s impression shows VFTS 352 — the hottest and most massive double star system to date where the two components are in contact and sharing material. The two stars in this extreme system lie about 160 000 light-years from Earth in the Large Magellanic Cloud. This intriguing pair could be heading for a …

TED-Ed: Where does gold come from?

Did you know that gold is extraterrestrial? Instead of arising from our planet’s rocky crust, it was actually cooked up in space and is present on Earth because of cataclysmic stellar explosions called supernovae. CERN Scientist David Lunney outlines the incredible journey of gold from space to Earth.  

AMNH: Science Bulletins | Exploring a Star’s Death in 3D

Cassiopeia A is the gas cloud left behind after a star exploded, first glimpsed on Earth about 325 years ago. Its youth and proximity to us make it one of the best-studied supernova remnants in our galaxy. Recent observations have made it possible for scientists to create the first map of the star’s interior in …

NASA Goddard: NASA Missions Take an Unparalleled Look into Superstar Eta Carinae

Eta Carinae is a binary system containing the most luminous and massive star within 10,000 light-years. A long-term study led by astronomers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, combined data from NASA satellites, ground-based observing campaigns and theoretical modeling to produce the most comprehensive picture of Eta Carinae to date. New findings …

BuzzFeedBlue: “209 Seconds That Will Make You Question Your Entire Existence”

A fun video by BuzzFeedBlue that puts the word “relative” in focus. We are indeed small in this universe, and this video makes this more than efficiently apparent. Every time you get upset about something small, just remember this.  

TRBQ: We Are Dead Stars

Every atom in our bodies was processed in the body of an ancient star, says NASA astronomer Dr. Michelle Thaller. Thaller explains how the iron in our blood connects us to one of the most violent acts in the universe—a supernova explosion—and what the universe might look like when the stars die out.  

Beakus: How Do We Know How Old The Sun Is?

In ‘How Do We Know How Old The Sun Is?’ ROG astronomer Brendan explains how we determine the age of our Solar System from space rocks and how we can work out how long the Sun has left before it engulfs the inner planets.  

ESO: The largest yellow star ever before seen

ESO reports that this hypergiant has been found to measure more than 1300 times the diameter of the Sun, and to be part of a double star system, with the second component so close that it is in contact with the main star.

Carolin Crawford: The Lives of Stars

Published on Feb 26, 2014 Professor Carolin Crawford answers every question you’ve ever had about the most romantic stellar bodies, the stars are an ubiquitous feature of our local Galactic environment. They do not last forever — but form, develop and evolve over timescales of millions or billions of years, eventually to expire in dramatic …

Cambridge: Gaia’s mission: Solving the celestial puzzle

A space mission to create the largest, most-accurate, map of the Milky Way in three dimensions will revolutionize our understanding of the galaxy and the universe beyond. On 19th December 2013, a rocket blasted into the sky from a launch site in French Guiana and travelled 1.5 million km to reach its destination in orbit …

American Museum of Natural History: Remote Reconnaissance of Another Solar System

This visualization, produced using the Hayden Planetarium’s Digital Universe–the most comprehensive and scientifically accurate, three-dimensional map of the known universe– shows where the star HR 8799 is in relation to our solar system. Recently, a team of researchers led by the American Museum of Natural History used a suite of high-tech instrumentation and software called …

Institute of Physics: How Big is the Universe?

This video by The Institute of Physics explains how astronomers have learnt to measure the distance to the stars. How many stars are in the observable universe and is it possible to comprehend the size of it all?

Institute of Physics: The Life Cycle of Stars

This video by The Institute of Physics explains how we believe stars are born, live and die and the different ends to different sized stars.

NASA: What is a Pulsar?

A pulsar is a neutron star that emits beams of radiation that sweep through Earth’s line of sight. Like a black hole, it is an endpoint to stellar evolution. The “pulses” of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star’s rotation axis and its magnetic axis. Pulsars …
