Controlled experiments are impossible in astronomy, as are direct measurements of physical properties of objects outside our solar system. So how do astronomers know so much about them?

Measuring the ages of planets and stars is tricky. An observational astrophysicist describes the subtle clues that provide good estimates for how old different space objects are.
Massive flashes of energy known as ‘fast radio bursts’ have puzzled astronomers for years – and a new search for links to gravitational waves has so far found no connection.

Canada’s partnership in the world’s largest radio telescope, located in South Africa and Australia, creates new opportunities for research, but the benefits go beyond astronomy.
Planetary analogues are sites on Earth that are so extreme that they replicate those of celestial bodies in our solar system.

Months after a military officer made sensational claims about unexplained objects in the skies, NASA released a report loosely outlining a scientific approach for analyzing UAP reports.
There’s a chance Nishimura might brighten unexpectedly – but it’s a slim one.

An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.
To the ǀXam and San people, being in the world as a person includes “the sky’s things” - an understanding of and deep connection with the cosmos.

Astronomer Caroline Herschel’s work discovering and cataloging astronomical objects in the 18th century is still used in the field today, but she didn’t always get her due credit.

Liftoff to the distant asteroid is scheduled for Oct. 5, 2023 – the beginning of a six-year journey to one of the most unusual objects in the solar system.
The universe used to be filled with a hydrogen fog, before early stars and galaxies burned through the haze. Astronomers are studying galaxies that tell them about this period in the early universe.
A mysterious hunk of space junk buzzed through Australian skies last night. It may have been the third stage of a Soyuz 2 rocket just launched by Russia.
