Some planets stand stark naked. For the first time, we have observational evidence that some super-Earths orbit so close to their host stars that the puffy atmospheres that clothed them have been ripped away.

Our solar system may have once been a much more crowded place than it is today.

A study has suggested at least one super-Earth sized planet may have formed in the early days of the solar system before being devoured by the sun.

At least one super-Earth — a planet that is larger than Earth, but smaller than Neptune — could have formed close to the Sun, suggests a new study.

A super-Earth may have once formed close to the sun.

Findings of a new study suggest that this young super-Earth formed after clearing up the solid objects that lay between the sun and Mercury. Unfortunately, this primordial world was eventually consumed by the solar system's star after succumbing to its gravity.

From studies of extrasolar systems, it is apparent that planetary systems around other stars are as varied as the planets they contain and that no one system is like another. Nonetheless, more than half of the observed Sun-like stars in the solar neighbourhood have one or more super–Earth planets that orbit their host star within days to months - a feature that is lacking in our own Solar System. So, why isn’t Earth accompanied by a much larger neighbor?

There are few things more frustrating when traveling by air than waiting patiently for your "zone" to be called at the gate, walking down the jetway like a boss, and then, inexplicably, being met by a sudden and immovable line in the plane's narrow aisle.

Listener Hutch Humphreys of San Diego sent Marketplace this question: “I was wondering what research has gone into the various algorithms airlines use for boarding passengers, and why most of those algorithms do not seem to work very well.”

There’s only one planet in our solar system that can communicate across interplanetary space. But imagine if things were different. Say if Mars, for example, had intelligent beings able to talk to us at the same time as we talked to them — how would that have changed our history?

More than 1,900 exoplanets or alien planets are present around other stars. Now, a new research has claimed that these alien planets can help each other in their existence. The researchers said that alien planets present close to each other around the same parent star can help each other when it comes to supporting life, creating ‘multihabitable systems’.

There are planets close enough to each other that could share life and boost its survival, a new study suggests. Scientists are exploring the potential presence of "multihabitable systems," planetary systems with more than one habitable planet.

Aside from a handful of astronauts, the only living beings to have seen an inhabited planet looming large in the sky come from science fiction.

Is there life on other planets? A recent study by Jason Steffen from the University of Nevada in Las Vegas is shedding new light on this persistently challenging question.
