Explainer: Mars rover discovers building blocks of life on the red planet

The discovery is said to be the most compelling evidence that billions of years ago, the parched Red Planet once consisted of carbon-based compounds essential to sustain life. In addition to finding organic molecules in the rocks in Gale Crater , rover scientists are reporting another intriguing finding. "That gives me great hope because we can perhaps get past these surface environments that are so harsh and maybe [go] a little deeper and find better-preserved materials".

Juno Spacecraft Solves 39-Year Old Mystery of Jupiter Lightning

The other study, published in the journal Nature , unveiled that lighting on Jupiter produces not only kilohertz emissions, the singular radio range detected by Voyager 1 almost four decades ago, but also gigahertz radio waves, just like lightning on Earth .



'Earliest animal fossil footprints discovered in China'

They are often assumed to have appeared and radiated suddenly during the Cambrian Explosion about 541 to 510 million years ago, although it has always been suspected that their evolutionary ancestry was rooted in the Ediacaran Period. Prior to this, animal life on Earth consisted of simpler, single-celled or multicellular organisms, but the Cambrian Period gave rise to more complex creatures of a kind we recognise today, including bilaterian animals, who exhibited the first bilateral ...


Season's 1st tropical storm forms in eastern Pacific

Season's 1st tropical storm forms in eastern Pacific

In the last 70 years the storms have slowed by ten per cent. At the same time, related research published just last month suggests that warming temperatures from climate change will slow storms more in the future. Dr Christina Patricola , from the Climate and Ecosystems Sciences Division at University California, Davis, says the findings raise several questions, especially regarding "stalled" tropical cyclones.
