Visitors are discouraged from the remote desert location where powerful telescopes are listening to the universe.
There’s an extensive range of telescopes, mounts and accessories on the market, and trying to pick from it might have you seeing stars. Here’s what the experts suggest.
Once featured in movies, TV shows and video games, the Arecibo Observatory was the pride of Puerto Rico.

The collapse of the Arecibo Observatory in Puerto Rico was a result of financial neglect – and was a long time coming.
With the proper equipment, you can enjoy the beauty of the night sky.

COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
Diligence, technological progress and a little luck have together solved a 20 year mystery of the cosmos.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
Today we hear about some of the fascinating space research underway at Siding Spring Observatory – and how, despite gruelling hours and endless paperwork, astronomers retain their sense of wonder for the night sky.
‘The size, the grandeur, the peacefulness of being in the dark’: what it’s like to study space at Siding Spring Observatory.

Mysterious cosmic flashes known as gamma-ray bursts are caused by the death throes of massive stars.
Two lenses might be better than one.
There’s really no reason you can’t use binoculars to look into space – and in fact astronomers have been working on doing so for a long time.

For the first time scientists have located the home galaxy of a one-off fast radio burst. Here’s how they did it – and what they learned about the galaxy.
Planets form from a disc of dust orbiting a star.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star’s chemistry to predict which ones are likely to host giant planets.

When you look up at the vastness of space you can see hundreds, thousands and even millions of years into the past.
Enjoying the planets lined up in a row.
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.

About 5 percent of all UFO sightings cannot be easily explained by weather or human technology. A physicist argues that there’s compelling evidence to justify serious scientific study and that the skeptics should step aside – for the sake of humanity.
The things you can do with an amaterur telescope.
With a little bit of knowledge and a few pieces of equipment you too can look at the night sky and see it as a cosmologist does.
