World celebrates centenary of confirmation of relativity

World celebrates centenary of confirmation of relativity Celebrations are underway across the globe to commemorate 100 years since a UK-led expedition confirmed Einstein’s general theory of relativity. The theory fundamentally changed our understanding of physics and astronomy, and underpins critical modern technologies such as the satellite-based Global Positioning System (GPS). A series of public events […]

Meteor magnets in outer space—study finds elusive giant planets

Meteor magnets in outer space—study finds elusive giant planets Astronomers believe planets like Jupiter shield us from space objects that would otherwise slam into Earth. Now they’re closer to learning whether giant planets act as guardians of solar systems elsewhere in the galaxy. phys.org Go to Source

Hubble spies curious galaxy moving a little closer

Hubble spies curious galaxy moving a little closer This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong. phys.org Go to Source

Video: 100 years of gravity

Video: 100 years of gravity One hundred years ago this month, observations performed during a total solar eclipse proved for the first time the gravitational bending of light predicted by Albert Einstein’s new theory of gravity, general relativity. In this video, Günther Hasinger, ESA Director of Science, reflects on this historic measurement that inaugurated a […]

New catalogue of 12,000 X-ray spectral lines

New catalogue of 12,000 X-ray spectral lines X-ray sources in the sky radiate “bar codes” revealing their properties. These bar codes consist of narrow peaks and troughs within the source’s spectrum. The RGS instrument on the satellite XMM-Newton was built to find these bars—or spectral lines. Astronomer Junjie Mao and his colleagues at SRON and […]

A family of comets reopens the debate about the origin of Earth’s water

A family of comets reopens the debate about the origin of Earth’s water Where did the Earth’s water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans.  Now, however, an international team, bringing together CNRS researchers at the […]

€17 million Fund Backs 170 Breakthrough Concepts in Imaging and Sensing

€17 million Fund Backs 170 Breakthrough Concepts in Imaging and Sensing ATTRACT, a Horizon 2020 research and innovation project funded by the European Union and backed by a consortium of 9 partners including ESO, has announced 170 breakthrough ideas which will each receive €100,000 to develop technologies that have the potential to change society. The […]

Chemistry of stars sheds new light on the Gaia Sausage

Chemistry of stars sheds new light on the Gaia Sausage Chemical traces in the atmospheres of stars are being used to uncover new information about a galaxy, known as the Gaia Sausage, which was involved in a major collision with the Milky Way billions of years ago. phys.org Go to Source

A unique experiment to explore black holes

A unique experiment to explore black holes What happens when two supermassive black holes collide? Combining the observing power of two future ESA missions, Athena and LISA, would allow us to study these cosmic clashes and their mysterious aftermath for the first time. phys.org Go to Source

New ultra diffuse galaxy found in the NGC 5846 group

New ultra diffuse galaxy found in the NGC 5846 group Astronomers have detected a new ultra diffuse galaxy (UDG) located most likely in the NGC 5846 galaxy group. The discovery is part of the ongoing VEGAS survey aimed at investigating early-type galaxies in a range of environments. Details of the finding were presented in a […]

Galaxies as ‘cosmic cauldrons’

Galaxies as ‘cosmic cauldrons’ Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic systems, like “cosmic cauldrons,” consisting of components that constantly change their appearance. Based on new observations of the […]

Neptune’s moon Triton fosters rare icy union

Neptune’s moon Triton fosters rare icy union Astronomers using the Gemini Observatory explore Neptune’s largest moon Triton and observe, for the first time beyond the lab, an extraordinary union between carbon monoxide and nitrogen ices. The discovery offers insights into how this volatile mixture can transport material across the moon’s surface via geysers, trigger seasonal […]
