Sun emits a mid-level solar flare

ENLARGE / The sun emitted a mid-level solar flare, peaking at 9:03 a.m. EDT on April 18, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however — when intense […]

Continents may be a key feature of Super-Earths

Huge Earth-like planets that have both continents and oceans may be better at harboring extraterrestrial life than those that are water-only worlds. A new study gives hope for the possibility that many super-Earth planets orbiting distant stars have exposed continents rather than just water-covered surfaces. A video still showing an artist's impression of an alien […]

Hands on with Ubuntu 14.04: The best Ubuntu desktop ever

Lately, Ubuntu has been getting a lot of flack from other Linux users for going its own way. For example, Canonical, Ubuntu's parent company, eventually plans on using its own Mir display server instead of the more broadly supported Wayland, and that's annoyed many non-Ubuntu Linux developers.  That "inside baseball" criticism aside, I've found the latest release of Ubuntu […]

East African honeybees are safe from invasive pests… for now

Bassenthwaite female osprey returns to nest

Ospreys returned to the Lake District in 2001, after an absence of more than 150 years Enlarge A female osprey which produced two chicks last year has returned to the same nest in the Lake District. Ringed as KL, she successfully mated at the site last year with an unringed male after ousting a female […]

Dynamic atolls give hope that Pacific Islands can defy sea rise

It is widely predicted that low-lying coral reef islands will drown as a result of sea-level rise, leaving their populations as environmental refugees. But new evidence now suggests that these small islands will be more resilient to sea-level rise than we thought. The tiny Pacific nation of the Marshall Islands could avoid being swamped entirely, […]

Astronomers discover first self-lensing binary star system

ENLARGE / Geometry and light curve of the KOI-3278 system. As the white dwarf orbits a G dwarf (sun-like star) in this system, when the white dwarf passes in front of the G dwarf, it causes gravitational magnification, resulting in a pulse with a duration of 5 hours and height of 0.1%, while when it passes […]

How mighty Jupiter could have changed Earth’s habitability

Is Jupiter a friendly planet, Earth's enemy, or perhaps both? For decades, scientists have talked about how the giant gas planet keeps some asteroids from striking our small world, while others have pointed out that Jupiter's gravity could send some civilization-shattering asteroids our way. Jupiter as imaged by NASA's Galileo spacecraft, with the moon Europa's […]
