Astronomers Are Closing in on The Precise Moment The Universe Lit Up
A team of scientists working with the Murchison Widefield Array (WMA) radio telescope are trying to find the signal from the Universe’s first stars. Those first stars formed after the Universe’s Dark Ages.
NASA Astronaut Breaks Down Space Scenes From Film & TV
NASA astronaut Nicole Stott examines scenes depicting space from movies and television and breaks down how accurate they really are. What actually happens when your helmet cracks in space like in Total Recall? Are the spacewalks in Gravity realistic? Could there really be AI on a space station like in 2001: A Space Odyssey?

Mapping our galaxy’s magnetic field
Astronomers from CSIRO and Curtin University have used pulsars to probe the Milky Way’s magnetic field. Working with colleagues in Europe, Canada, and South Africa, they have published the most precise catalogue of measurements towards mapping our Galaxy’s magnetic field in 3D.
The Milky Way’s magnetic field is thousands of times weaker than Earth’s, but is of great significance for tracing the paths of cosmic rays, star formation, and many other astrophysical processes. However, our knowledge of the Milky Way’s 3D structure is limited.
Dr. Charlotte Sobey, the lead author of the research paper, said “We used pulsars (rapidly-rotating neutron stars) to efficiently probe the Galaxy’s magnetic field in 3D. Pulsars are distributed throughout the Milky Way, and the intervening material in the Galaxy affects their radio-wave emission.”
Our place in the universe will change dramatically in the next 50 years – here’s how
In 1900, so the story goes, prominent physicist Lord Kelvin addressed the British Association for the Advancement of Science with these words: “There is nothing new to be discovered in physics now.”
How wrong he was. The following century completely turned physics on its head. A huge number of theoretical and experimental discoveries have transformed our understanding of the universe, and our place within it.
Don’t expect the next century to be any different. The universe has many mysteries that still remain to be uncovered—and new technologies will help us to solve them over the next 50 years.
