All in the family: Kin of gravitational wave source discovered
Posted by Genevieve Klien in categories: physics, space
On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same source—a merger of two neutron stars. Now, a team that includes several University of Maryland astronomers has identified a direct relative of that historic event.

Physics: Not everything is where it seems to be
Posted by Genevieve Klien in categories: particle physics, quantum physics, space
Scientists at TU Wien, the University of Innsbruck and the ÖAW have for the first time demonstrated a wave effect that can lead to measurement errors in the optical position estimation of objects. The work now published in Nature Physics could have consequences for optical microscopy and optical astronomy, but could also play a role in position measurements using sound, radar, or gravitational waves.
With modern optical imaging techniques, the position of objects can be measured with a precision that reaches a few nanometers. These techniques are used in the laboratory, for example, to determine the position of atoms in quantum experiments.
“We want to know the position of our quantum bits very precisely so that we can manipulate and measure them with laser beams,” explains Gabriel Araneda from the Department of Experimental Physics at the University of Innsbruck.

A first look at China’s Mars simulation base out in the Gobi Desert
Posted by Klaus Baldauf in categories: climatology, space
China’s first Mars simulation base opened to the press on Friday in Gansu Province in the northwest of the country, providing a glimpse of the project mainly intended to popularise space among youth.
The base is located in the Gobi Desert, 40 kilometres away from the downtown area of Jinchang, a city in Gansu. The natural features, landscape and climate are being described as resembling Martian conditions.

Five in a row—the planets align in the night sky
Posted by Genevieve Klien in category: space
For the second time this year, the five brightest planets can be seen at the same time. You can catch them by looking towards the western sky after sunset. The planets will form a line rising up from the horizon.
Mercury and Venus are low to the west, with bright Jupiter shining just above. Higher up in the northwestern sky is Saturn, and completing the set of five is the red planet Mars, high overhead.
