Dark matter and dark energy: Do they really exist?

Wed, 22 Nov 17 00:13:20 -0800

Researchers have hypothesized that the universe contains a 'dark matter.' They have also posited the existence of a 'dark energy.' These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe. But -- according to a researcher at UNIGE -- these concepts may be no longer valid: the phenomena can be demonstrated without them. This research exploits a new theoretical model based on the scale invariance of the empty space.

Interstellar space probes: Where's the brakes?!

Fri, 17 Nov 17 00:09:40 -0800

With a miniaturised space probe capable of being accelerated to a quarter of the speed of light, we could reach Alpha Centauri, our nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past. A theoretical physicist at Goethe University Frankfurt has now examined whether interstellar spacecraft can be decelerated using 'magnetic sails'.

This is key information as humans and robotic missions venture out into the solar system, farther and farther from Earth.

Three-dimensional nanomagnets for the computer of tomorrow

Wed, 15 Nov 17 00:04:00 -0800

Since the late 60's electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.

Off track: How storms will veer in a warmer world

Wed, 15 Nov 17 00:03:50 -0800

Pluto's hydrocarbon haze keeps dwarf planet colder than expected

Wed, 15 Nov 17 00:10:30 -0800

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 published November 16 in Nature proposes a novel cooling mechanism controlled by haze particles to account for Pluto's frigid atmosphere.

The anatomy of a cosmic snake reveals the structure of distant galaxies

Mon, 13 Nov 17 00:14:10 -0800

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 from the universities of Geneva and Zurich have tackled this inconsistency and found the first answers thanks to the observation of the cosmic snake.

The paper also states that earthquake signatures for mid-latitude KFU ionosonde can be up to 3 times more prominent than on a low-latitude ionosonde in Japan.

Astronomers discover sunscreen snow falling on hot exoplanet

Thu, 26 Oct 17 00:08:20 -0700

Astronomers at Penn State have used the Hubble Space Telescope to find a blistering-hot giant planet outside our solar system where the atmosphere 'snows' titanium dioxide -- the active ingredient in sunscreen. These observations are the first detections of this 'snow-out' process, called a 'cold trap,' on an exoplanet. The research provides insight into the complexity of weather and atmospheric composition on exoplanets, and may someday be useful for gauging the habitability of Earth-size planets.
