Water Is Destroyed, Then Reborn in Ultrahot Jupiters

Water Is Destroyed, Then Reborn in Ultrahot Jupiters

Imagine a place where the weather forecast is always the same: scorching temperatures, relentlessly sunny, and with absolutely zero chance of rain. This hellish scenario exists on the permanent daysides of a type of planet found outside our solar system dubbed an "ultrahot Jupiter." These worlds orbit extremely close to their stars, with one side of the planet permanently facing the star.

Water, water, everywhere in our Solar system but what does that mean for life

Water, water, everywhere in our Solar system but what does that mean for life

There was much excitement when NASA recently revealed new details about the oceans that lurk beneath the surface of Saturn’s tiny moon Enceladus and Jupiter’s Europa. Why the excitement? Well, here on Earth, where you have water, energy and nutrients, you have life. So why not life on these other worlds?

First Light for Band 5 at ALMA - New receivers improve ALMA’s ability to search for water in the Universe

The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile has begun observing in a new range of the electromagnetic spectrum. This has been made possible thanks to new receivers installed at the telescope’s antennas, which can detect radio waves with wavelengths from 1.4 to 1.8 millimetres — a range previously untapped by ALMA. This upgrade allows astronomers to detect faint signals of water in the nearby Universe.
