We can't use tape measures, rulers or lasers to measure the astronomical distances to stars and galaxies, so how do we do it?

One of the Hubble Space Telescope’s most iconic images is the Hubble Ultra Deep Field, which unveiled myriad galaxies across the universe, stretching back to within a few hundred million years of the Big Bang....

Astrophyscists and astonomers will use the James Webb Space Telescope to unravel mysteries about the evolution of the Universe. The Webb telscope will help observe how the first stars gathered into the first galaxies, and those first...

The concept of the cosmic calendar was popularized by famous astronomer Carl Sagan to help people understand just how far apart on a time scale events in the Universe are. Basically, he arranged the 13.8 billion years of the Universe’s...

What is space science? What fields does a space scientist study? In this program students will learn that space scientists work in many non-engineering fields including astrophysics, cosmochemistry, planetary geology space weather and...

We all know the perfect, symmetrical and flawless galaxies Hubble has set its lense on, but there is also a catalogue dedicated to the most peculiar galaxies out there... The Arp Catalogue

In this week's episode, we explore cockroaches that provide clues to better locomotion, virtual reality therapy, and distant galaxies seen from the South Pole

Hubble has taken some spectacular images of many different galaxies, but it can't resolve more than a few blobs on Pluto's surface. Why is that?

Measurements of unprecedented detail returned by Japan's Hitomi satellite have allowed scientists to track the motion of X-ray-emitting gas at the heart of the Perseus cluster of galaxies for the first time. The...

James Webb Space Telescope Program Director Greg Robinson discusses NASA's largest and most powerful space science telescope ever constructed.

Time and space can be a bit baffling. The universe is expanding, but from which point? Where is the centre of the universe?

Astronomer Steve Eikenberry at the University of Florida is on the hunt for black holes. Using a custom built camera affixed to the Gemini South telescope in Chile, he is honing in on the supermassive black hole at the center of our...

Astrum shows what a supervoid really is, and explains why this image isn't one.

A new computer simulation tracking dark matter particles in the extreme gravity of a black hole shows that strong, potentially observable gamma-ray light can be produced. Detecting this emission would provide astronomers with...

Three astronomers explain how Hubble acts like a time machine by detecting which galaxies are moving toward and away from us.<b<b<b<br/>r/>r/>r/>

Deep surveys by the James Webb Space Telescope will capture the full panorama of galaxy evolution, from the earliest dwarf galaxies that formed to the familiar galaxies we see today. The Webb Telescope will help us understand how the...

NASA's Hubble Space Telescope took an image of a bizarre, ghostly looking galaxy called NGC 1052-DF2 that astronomers calculate to have little to no dark matter. This is the first galaxy astronomers have discovered to be so...

When will the next naked-eye supernova event happen? What will it look like? Will we be safe?

Astronomer Steve Eikenberry at the University of Florida is on the hunt for black holes. Using a custom built camera affixed to the Gemini South telescope in Chile, he is honing in on the supermassive black hole at the center of our...

A look at the James Webb Space Telescope, its mission and the incredible technological challenge this mission presents. Credit: NASA's Goddard Space Flight Center Michael McClare (KBRwyle): Lead Producer Michael McClare (KBRwyle): Lead...

Astrophysicists and astronomers will use the James Webb Space Telescope to see further than Hubble to witness the origin and development of galaxies. <b<b<br/>r/>r/>

The Hubble Space Telescope has made over 1.5 million observations since its launch in 1990, capturing stunning subjects such as the Eagle Nebula and producing data that has been featured...

The Hubble Space Telescope captured an image of a quasar named 3C 186 that is offset from the center of its galaxy. Astronomers hypothesize that this supermassive black hole was jettisoned from the center of its galaxy by...

In this video, we explore the concept of how telescopes allow us to see objects that are light years away, giving us a glimpse into the past. By understanding how light reflects off objects and travels to our eyes, we can comprehend how...
