An international team of astronomers has completed the most comprehensive ultraviolet survey of the local universe to date, with the help of the Hubble Space Telescope. The survey could help scientists better understand how stars come to form, and how galaxies like our own evolve over time.

Our universe seems to contain a suspiciously perfect amount of "dark energy" to sustain life. But new research suggests that life is still possible even with far more dark energy than we have, and the results have some big implications for the multiverse theory.

Renowned physicist Stephen Hawking passed away earlier this year, but his legacy to science will live on. His final theory on the origin of the universe has now been published, and it offers an interesting departure from earlier ideas about the nature of the “multiverse.”

The world's largest radio telescope is taking shape. The Square Kilometre Array will be of a scale never seen before, and with the first prototype dish recently unveiled, the search for answers to some of the most fundamental questions about the universe and its origins is set to begin.

To look through space is to look through time. Astronomers have now peered right back to the “Cosmic Dawn” – when the first stars were beginning to fire up – by picking up an extremely faint radio signal that marks the earliest evidence of hydrogen, just 180 million years after the Big Bang.

The first intriguing findings have been released from the Dark Energy Survey, a project studying the mysterious force that seems to be accelerating the expansion of the universe. The study has discovered 11 new stellar streams, the remains of other galaxies that our own Milky Way has torn to shreds.

In 2017 we witnessed a solar eclipse cross the US, welcomed an interstellar visitor, and discovered some exciting Earth-sized exoplanets. Some astonishing images of the farthest reaches of our universe were also captured. Here we collect some of the most awe-inspiring space images of 2017.

At a distance of about 13 billion lightyears, the most distant supermassive black hole known so far has been spotted. That incredible distance means it dates back to when the first stars blinked on, which raises the question of how a black hole that big arose so soon after the universe began.

Next time you’re untangling your earbuds, remember that knots may have played a crucial part in kickstarting our universe, and without them we wouldn’t live in 3D. That’s the strange story pitched by physicists in a new paper, to help plug a few plot holes in the origin story of the universe.

The Lambda Cold Dark Matter model suggests that 68 percent of the universe is made up of dark energy. But a new study has questioned whether dark energy exists, citing simulations that found that accounting for the structure of the cosmos, the gap in the theory, which dark energy fills, vanishes.
