A star 500 million lightyears away appears to be a Matryoshka doll of puzzles.

… and with that, dark matter is not far behind.

When Victor Buso was photographing the night sky in September 2016, he had a one in 10 million chance that he'd capture a supernova. The universe made sure he took it.

What's the Falcon Heavy? Why did it launch a car into space? Who was at the wheel? Isn't the car space junk? Was there a point to all this beyond vanity?

In conversation with Sanghamitra Bandyopadhyay on microRNA, machine learning, computational biology and open science.

An interview with the notable physicist Nathan Seiberg on string theory, particle colliders, physics of the future and research in India.

The star-planet system is zipping towards Earth. In about 79,000 years, they will replace Proxima Centauri and Proxima b as our closest star and closest potentially habitable exoplanet, respectively.

Two neutron stars collided in space, unleashing a deadly beam of gamma rays, spewing heavy metals into the cosmos and drawing the attention of over 70 observatories worldwide. The universe doesn't get more breathtaking.

There’s clearly something mysterious going on. We don’t know what it is or how it works and we’re as close to figuring it out as we were in 2009.

It seems what everyone has been wishing for all along will also be the only thing that will be able to settle this back-and-forth – but that’s not going to happen soon.

While astronomers are not going to bother including it in our continuing search for alien life, the planet itself will not be able to look forward to a charmed existence.

A planet’s atmosphere is what we need to be studying the most if and when we’re looking for signs of life.

Lucy and Psyche are a part of NASA's Discovery Program, whose raison d'être is to explore our planetary neighbourhood using "faster, better, cheaper" missions.

The asteroid chunk was nearly 15 km in diameter and hit Earth at faster than 20 km per second – imagine a Mt-Everest-sized rock slamming down from space at Mach 58.

It will be the first time in history that a rocket, ISRO's PSLV, will be launching two rovers to the Moon in a single mission.

The latter half of this year has had a generous dose of supermoons and that will persist. The previous one was last month. The next supermoon is next month, on December 14.

The last known supercontinent had broken up to yield two oceans. Dinosaurs were rampant on the globe, on land, in water and in the skies and the first flowers were showing. The Triassic was almost lovely.

This mission will be followed in 2020 by a rover on the red planet, joining NASA's Curiosity and Opportunity in assessing if Mars possesses, or possessed, any life at all.
