Lava or not, exoplanet 55 Cancri e likely to have atmosphere

Science Daily Astronomy - Thu, 2017-11-16 11:37
Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. Now, a new analysis finds this planet likely has an atmosphere whose ingredients could be similar to those of Earth's atmosphere, but thicker.

Pluto's hydrocarbon haze keeps dwarf planet colder than expected

Science Daily Astronomy - Wed, 2017-11-15 13:09
The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere. For the dwarf planet Pluto, however, the predicted temperature based on the composition of its atmosphere was much higher than actual measurements taken by NASA's New Horizons spacecraft in 2015. A new study proposes a novel cooling mechanism controlled by haze particles to account for Pluto's frigid atmosphere.

Listening for gravitational waves using pulsars

Science Daily Astronomy - Wed, 2017-11-15 09:25
When galaxies collide, their central black holes tend to spiral toward each other, releasing gravitational waves in their cosmic dance. To explore this uncharted area of gravitational wave science, researchers look a natural experiment in the sky called a pulsar timing array. Pulsars are dense remnants of dead stars that regularly emit beams of radio waves, which is why some call them "cosmic lighthouses."

Closest temperate world orbiting quiet star discovered

Science Daily Astronomy - Wed, 2017-11-15 09:17
A temperate Earth-sized planet has been discovered only 11 light-years from the solar system by a team using ESO's unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life.

Gravitational waves from merging supermassive black holes will be spotted within 10 years

Science Daily Astronomy - Mon, 2017-11-13 12:36
New research predicts that gravitational waves generated by the merger of two supermassive black holes -- the strongest gravitational waves in the universe -- will be detected within 10 years. The study is the first to use real data, rather than computer simulations, to predict when such an observation will be made.

Anatomy of a cosmic snake reveals structure of distant galaxies

Science Daily Astronomy - Mon, 2017-11-13 11:11
We have a fair understanding of star formation, from the interstellar matter to the diffuse clouds whose gravitational contraction gives birth to stars. But observations of distant galaxies have questioned this picture, the size and mass of these distant stellar nurseries exceeding that of their local counterparts. Astrophysicists have tackled this inconsistency and found the first answers thanks to the observation of the cosmic snake.
