Atmosphere Detected Around A Small Super-Earth

If we want to discover signs of life on an exoplanet, our best option is to study its atmosphere, which is easier said than done. The exoplanets whose atmospheres have been studied so far don’t seem to have what we would consider ‘life-friendly’ conditions. But

The Ethics of Timetravel

I recently talked about how time travel to the past is unlikely to be possible. That came with the label that we haven’t found a law that tells us that it’s impossible just yet. We have hints, but no certainty. So what if time travel

Has anyone got a recipe for artificial gravity?

One of the underlying ideas in Einstein’s general relativity is that for an observer, the acceleration due to gravity, or the acceleration due to thrust, are identical. This is a consequence of the equivalence principle. This phenomenon is the way to achieve artificial gravity in

Travelling through the cosmos

Space is big. The Voyager probe, launched in 1977 to explore Jupiter and Saturn, took 36 years to leave the Solar System. It is the furthest human object from us, and it is still in our neighbourhood. Even the radio waves we sent into space
