Galaxy

Mapping the universe

By observing the universe at low radio frequencies, astronomers can now specify with greater accuracy the number of new stars being formed in the early universe, establish a correlation between the brightness of galaxies on the low radio images and the rate of star formation as well as analyse emissions from around massive black holes or the collision of galaxies.

In this episode of The Debrief, we speak to two astronomers helping to create the most detailed map ever of the universe.

Astronomers come up with most detailed map of the universe ever – and it’s out of this world

By observing the universe at low radio frequencies, astronomers can now specify with greater accuracy the number of new stars being formed in the early universe, establish a correlation between the brightness of galaxies on the low radio images and the rate of star formation as well as analyse emissions from around massive black holes or the collision of galaxies.

It’s The Debrief Christmas Special 2020!

It’s that time of year again for The Debrief Christmas Special! Hosted by John Beauchamp with guest Ed Wight, Managing Editor of The First News.

Astronomers discover smallest rogue planet in the galaxy

To locate the free-floating planet, a team of international astronomers led by those from the University of Warsaw’s OGLE team at the Astronomical Observatory used an astronomical phenomenon called gravitational microlensing.

Law of physics not universal, new research by Polish scientists finds

The discovery could help change the way the universe and the rule of physics are viewed.

Twinkle, twinkle little star: Polish satellites on the scene when a nova is born

The information from the satellites could help scientists understand how elements are spread across the galaxy.

Hole hunters: astronomers use pioneering technique to probe the blackness of space for elusive black holes

The technique, which has already unearthed stars, allows scientists to see what is invisible.

Comet from another GALAXY spotted heading through the Milky Way

If, as researchers believe, the 2l/Borisov comet comes from another galaxy this makes it a huge discovery: as the first comet from so far away and the second object from intergalactic space observed in the Solar System.

Astronomers create stunning 3D map of the Milky Way to study structure of the galaxy

The team from the University of Warsaw say their unique map, which was based on observing 2,400 stars less than 250 million years old, is more accurate than models currently in use.
