What is a quasar?
A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-quasar…
Water worlds may be abundant in our galaxy
A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Mlilky Way. Source: https://earthsky.org/space/water-common-on-planets-pebble-accretion-milky-way…

A new planet next door?
Astronomers have spotted “something” near Alpha Centauri A, in the star system nearest our Earth and sun. If it turns out to be a planet, it’ll be the first time a planet has been directly imaged within the habitable zone of a star.

Maarten Schmidt solves the puzzle of quasars
On February 5, 1963, Maarten Schmidt unraveled the mystery of quasars and pushed back the edges of the known cosmos. His insight into quasars – the most distant and luminous objects known – has changed the way scientists view the universe.
