Identifying biomolecule fragments in ionising radiation

When living cells are bombarded with fast, heavy ions, their interactions with water molecules can produce randomly scattered 'secondary' electrons with a wide range of energies. These electrons can then go on to trigger potentially damaging reactions in nearby biological molecules, producing electrically charged fragments. So far, however, researchers have yet to determine the precise energies at which secondary electrons produce certain fragments. In a new study published in EPJ D, researchers in Japan led by Hidetsugu Tsuchida at Kyoto University define for the first time the precise exact ranges in which positively and negatively charged fragments can be produced.

4.5-bil­lion-year-old ice on comet 'fluffi­er than cap­puc­ci­no froth'

After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center Philae Control Center. Philae left traces behind; the lander pressed its top side and the housing of its sample drill into an icy crevice in a black rocky area covered with carbonaceous dust. As a result, Philae scratched open the surface, exposing ice from when the comet was formed that had been protected from the Sun's radiation ever since. The bare, bright icy surface, the outline of which is somewhat reminiscent of a skull, has now revealed the contact point, researchers write in the scientific publication Nature.

Study shows comets impacted start of life on earth

The entire view is nearly 109,000 light-years across, approximately the diameter of our Milky Way.

An early dark energy model could solve an expanding cosmological conundrum

Much mystery surrounds dark energy and the cosmological constant, the proxies used to explain the accelerating expansion of the Universe. New research suggests that an early model of dark energy presents a competing theory that offers all the benefits of current models without the baggage that comes associated with the cosmological constant.

Measuring the expansion of the universe: The importance of measuring velocity

Ever since the astronomer Edwin Hubble demonstrated that the further apart two galaxies are, the faster they move away from each other, researchers have measured the expansion rate of the universe (the Hubble constant) and the history of this expansion. Recently, a new puzzle has emerged, as there seems to be a discrepancy between measurements of this expansion using radiation in the early universe and using nearby objects. Researchers from the Cosmic Dawn Center, at the Niels Bohr Institute, University of Copenhagen, have now contributed to this debate by focusing on velocity measurements. The result has been published in Astrophysical Journal.

Violent cosmic explosion revealed by ALMA: The merging of massive protostars?

The phenomenon of molecular outflow was first discovered in the 1980's. Very high velocity motions were detected in the line wings of the carbon monoxide (CO) molecule, seen towards young forming stars. The high velocity motions obviously could not be gravitationally bound motions (such as infall or rotation) because of the required large gravitating masses. The first detections were in fact in the extremely bright CO lines in the center of the Orion nebulae, which were already seen when CO was first detected in the interstellar medium.

Citizen astronomers reshape asteroids from their backyard

LIGO and Virgo announce 39 new gravitational wave discoveries during first half of third observing run

The LIGO Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a), and scientists have detected more than three times as many gravitational waves than the first two runs combined. Gravitational waves were first detected in 2015 and are ripples in time and space produced by merging black holes and/or neutron stars. Several researchers from Rochester Institute of Technology's Center for Computational Relativity and Gravitation (CCRG) were heavily involved in analyzing the gravitational waves and understanding their significance.

Asteroid Ryugu shaken by Hayabusa2's impactor

Professor Arakawa Masahiko (Graduate School of Science, Kobe University, Japan) and members of the Hayabusa2 mission discovered more than 200 boulders ranging from 30 cm to 6m in size, which either newly appeared or moved as a result of the artificial impact crater created by Japanese spacecraft Hayabusa2's Small Carry-on Impactor (SCI) on April 5th, 2019. Some boulders were disturbed even in areas as far as 40m from the crater center. The researchers also discovered that the seismic shaking area, in which the surface boulders were shaken and moved an order of centimeters by the impact, extended about 30m from the crater center. Hayabusa2 recovered a surface sample at the north point of the SCI crater (TD2), and the thickness of ejecta deposits at this site were estimated to be between 1.0mm to 1.8 cm using a Digital Elevation Map (DEM).

Impact craters reveal details of Titan's dynamic surface weathering

Scientists have used data from NASA's Cassini mission to delve into the impact craters on the surface of Titan, revealing more detail than ever before about how the craters evolve and how weather drives changes on the surface of Saturn's mammoth moon.
