The existence of a “Planet X” in the outer solar system was the subject of great speculation, and was finally settled with the discovery of Pluto in 1930.
From Twinkle Twinkle to Space Odyssey and beyond, humans have always turned to music to help deal with the profoundly confronting enormity of the cosmos. Is that a match made in the heavens?
The moon might harbor bits of the Earth that blasted off our planet billions of years ago. These lunar time capsules could hold secrets about conditions here at home back when life was first emerging.
Look up tonight and you’ll see a stunning conjunction of the two brightest planets in the night sky.
A unique map of the galaxies in the sky could shed light on the mysteries of the universe – including dark energy and dark matter.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Astronomers have spotted the earliest known stars in the universe, belonging to a class of chemically pure stars that may never have been seen before.
Cleo Loi was an undergraduate when she made a startling discovery. Her story shows how brilliance, dedication and imagination drive science.
Astronomers used to probing the universe always knew that strange signals detected by the Parkes radio telescope were coming from somewhere closer to home. But finding the source was the tricky bit.
Astronomers aren’t mere stargazers these days. One researcher explains the ins and outs of how they collect data from far-off galaxies and what they do with it back at the office.
After a slow start, Hubble’s ultraviolet vision changed the face of astronomy.
Astronomers from around the world identify their favourite images sent back to Earth by the Hubble Space Telescope.
An unremarkable speck in the sky was transformed into an unique astronomical object – and Hubble was there to capture it.
Hubble’s Deep Field images are the next best thing to a time machine, revealing details of galaxies from the early universe, 13 billion years ago.
Einstein’s theory of gravity says dark energy must be out there, accelerating the expansion of our universe. But what is it and how can we try to figure out more about it?
The Hubble Space Telescope launched 25 years ago in 1990. But O'Dell started on the project in 1972, garnering support for the world’s first telescope free of Earth’s atmosphere’s blurring effects.
Twenty-five years on and the Hubble Space Telescope is still taking some amazing images. But there have been a few glitches over the years, right from day one.
Scientists know so much about dark matter apart from what it is exactly. But are they getting any closer?
From a big blue marble to a tiny dot in space – reflections on our images of Earth.
