Building blocks of life would be technically detectable in our solar system
Researchers at Freie Universität Berlin Publish Study in the Journal Astrobiology. In the future, space missions would be at least technically capable of detecting DNA, lipids, and other components of bacteria on ocean moons in our solar system - if such building blocks of life exist outside Earth. This has now been demonstrated in laboratory experiments by an international team led by scientists from the Planetary Science and Remote Sensing Research Group at Freie Universität Berlin.

Exceptionally luminous jets: when a star meets a black hole
For the first time in over a decade, scientists from the CNRS and the Institut de radioastronomie millimétrique 1 , together with international colleagues, have observed a tidal disruption event (TDE

Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe. The signal, named AT 2022cmc, was discovered earlier this year by the Zwicky Transient Facility in California. Findings published today in Nature Astronomy, suggest that it is likely from a jet of matter, streaking out from a supermassive black hole at close to the speed of light.

Small asteroids are probably young
The impact experiment conducted on the asteroid Ryugu by the Japanese Hayabusa2 mission which took place two years ago resulted in an unexpectedly large crater. With the use of simulations, a team led by the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has recently succeeded in gaining new insights from the experiment regarding the formation and development of asteroids.

Mapping the chemistry of the Earth’s mantle
The Earth's mantle makes up about 85% of the Earth's volume and is made of solid rock. But what rock types is the mantle exactly made of, and how are they distributed throughout the mantle? An international team of researchers - including UT researcher Dr Juan Carlos Afonso (Faculty of ITC) - have been able to reveal the existence of pockets of rocks with abnormal properties that suggest that they were once created at the surface, transported to vast depths along subduction zones, and accumulated at specific depths inside the Earth's mantle.

Deepest look yet into the heart of a quasar
International team observes innermost structure of quasar 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active types of galaxy centres. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, presents new observations of the first quasar ever identified.

Non-detection of key signal allows astronomers to determine what the first galaxies were - and weren’t - like
Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

For female astronomers, pandemic widened publishing’s gender gap
Women comprise about 20% of all astronomers worldwide, but their productivity, as measured by annual number of publications, has lagged behind that of their male colleagues. The COVID-19 pandemic set them back even more, a new study finds. Before the COVID-19 pandemic abruptly shut down labs and sent scientists home to work, female astronomers on average published about nine papers for every 10 published by men - a rate that has remained stagnant for decades.

Catching the dynamic Coronal Web
Researchers discover an important clue as to what mechanism drives the solar wind Using observational data from the U.S. weather satellites GOES, a team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany has taken an important step toward unlocking one of the Sun-s most persevering secrets: How does our star launch the particles constituting the solar wind into space? The data provide a unique view of a key region in the solar corona to which researchers have had little access so far.

Shock waves trigger black holes’ powerful jets
Powerful jets of material released by black holes are accelerated far into space by shock waves within the jets, an international collaboration involving UCL researchers has found. The study, published in Nature , helps to solve a decades-old mystery about how these jets are produced. The research team was able to rule out alternative causes of the jets - such as magnetic reconnection - and, out of a number of theoretical models of how the particles in the jets are accelerated, showed that just one model was correct.

NASA’s Webb Reveals an Exoplanet Atmosphere as Never Seen Before
NASA's James Webb Space Telescope just scored another first: a molecular and chemical profile of a distant world's skies. This is shown in five new articles by an international team of scientists, including Jean-Michel Désert, Hinna Shivkumar and Saugata Barat from the University of Amsterdam are soon to be published in leading science magazines.

International team observes innermost structure of quasar jet
New observations show the deepest parts of the quasar's plasma jet in a project led by MIT Haystack Observatory. At the heart of nearly every galaxy lurks a supermassive black hole. But not all supermassive black holes are alike: there are many types. Quasars, or quasi-stellar objects, are one of the brightest and most active types of supermassive black holes.

Black holes in eccentric orbit
A research team from Jena and Turin (Italy) has reconstructed the origin of an unusual gravitational wave signal. As the researchers write in the current issue of the scientific journal "Nature Astronomy", the signal GW190521 may result from the merger of two massive black holes that captured each other in their gravitational field and then collided while spinning around each other in a rapid, eccentric motion (DOI: 10.1038/s41550'022 -01813-w).

Worldwide dataset captures Earth in finest ever detail
A global open-source dataset of high-resolution images of Earth - the most extensive and detailed of its kind - has been developed by experts led by UCL with data from the European Space Agency (ESA). The free dataset, WorldStrat, will be presented at the NeurIPS 2022 conference in New Orleans. It includes nearly 10,000km² of free satellite images, showing every type of location, urban area and land use from agriculture, grasslands and forests to cities of every size and polar ice caps.

Webb Space Telescope reveals birth of galaxies, how universe became transparent
Key takeaways: UCLA astrophysicists are among the first scientists to use the James Webb Space Telescope to get a glimpse of the earliest galaxies in the universe. The studies reveal unprecedented detail about events that took place within the first billion years after the Big Bang. The UCLA projects were among a small number selected by NASA to test the capabilities of the Webb telescope.
