Seeing 2.4 Billion Years Into The Past
Travel 2.4 billion light years back in time to see a strange object: Quasar 3C-273. With your own eyes.

The stars around Sirius make up the constellation of Canis Major which has some really nice open clusters to view through binoculars or a telescope.
This is all about our Sun, Solar System and our Galaxy and how they all fit together.
This is a fly around of the area of Mars that the Perseverance rover will operate in.
This video shows the position of Matariki relative to the Sun in mid-July. The video shows the night sky in the east throughout the whole night finishing with the sunrise.
We often just assume that our Earth is a puny little rock and these massive objects meander around the galaxy swallowing up unsuspecting planets. This is not the case, black holes can have massive mass but are only physically very small, as are neutron stars and white dwarfs.
The position of stars can be described by coordinates that resemble that way we describe positions on the Earth’s surface.
Telescopes are our window into the universe but they can also burn a big hole in your wallet and be a huge source of frustration if you don’t get the right one.
This short video shows you how to find the constellation of Sagittarius.
In this little video we’ll show you how to find the beautiful Sombrero Galaxy. This is easy to spot and is a very distinctive looking galaxy. The galaxy is about 28 million light years away near the constellation of Corvus. We start by showing you how to find Corvus and assume you already know how to find the Southern Cross. If you don’t know how to find the Southern Cross then watch our video called “How to Find The Southern Cross”. Try this out and let us know if you found the Sombrero Galaxy.
This is a short description of the constellation of Scorpius and some of the stars it contains.
Fly through of the Pleiades star cluster, known as Matariki in New Zealand in May/June. Made from ESA’s Gaia DR2 data.
Today at 2:35 was the last Supermoon for 2020 but the Moon will not rise until tonight so it will be passed the phase of Full Moon when it does. If you get a chance, go outside and have a look. If you miss it, don’t worry, it’ll be back next year.
(And we can do something about it.)
Life needs CHNOPS, the six essential elements Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulphur. Curiosity found them on ancient Mars, but a new study shows Earth was born without them. Only a lucky impact with Theia made our world habitable. In contrast, Venus never stood a chance. Meet the three planetary siblings and discover why only Earth became a cradle for life.
Mars’s mantle contains ancient fragments up to 4km wide from its formation—preserved like geological fossils from the planet’s violent early history.
Cosmic rays are hitting the atmosphere constantly. One of the products of the collisions is muons, and we can detect muons on the surface of the Earth to learn about the cosmic rays.
