Analysis: A spacecraft is starting to unravel the sun’s biggest mysteries
NASA's Parker Solar Probe is going closer to the sun than any spacecraft has been before - Dr Daniel Verscharen (UCL Space & Climate Physics) writes about the findings so far. If you ask a child to paint a picture of the sun, you will most likely get a bright yellow circle on a piece of paper. This is actually quite accurate, given that the sun is a ball of hot gas and that its surface (called the photosphere) mostly shines in bright yellow light.

Researchers named among world's best
Researchers named among world’s best
Durham researchers named among world's best At Durham we've long had a global reputation for the high standard and impact of our research. Now we're celebrating because five of our researchers have been named among the world's best for the quality and influence of their work. The researchers are investigating the origins of the universe, nature-based answers to climate change, and the make-up of the Earth's crust.

Closest-ever approach to the Sun gives new insights into the solar wind
Closest-ever approach to the Sun gives new insights into the solar wind
The Parker Solar Probe spacecraft, which has flown closer to the Sun than any mission before, has found new evidence of the origins of the solar wind. NASA's Parker Solar Probe was launched in August 2018. Its first results are published today in a series of four papers in Nature , with Imperial College London scientists among those interpreting some of the key data to reveal how the solar wind is accelerated away from the surface of the Sun.

Parker Solar Probe’s first discoveries: Odd phenomena in space weather, solar wind
Last summer, NASA's Parker Solar Probe split the predawn skies in a blaze of light as it headed closer to the sun than any other spacecraft. Named for pioneering University of Chicago astrophysicist Eugene Parker, the probe has now made three of its 24 planned passes through the sun's corona-enough for scientists to announce their first discoveries.  In four papers published Dec.

Analysis: We may have solved the mystery of how landslides form on Mars
Mars's huge landslides can move at speeds of up to 360 kilometres an hour for up to tens of kilometres. PhD candidate Giulia Magnarini and Dr Tom Mitchell (UCL Earth Sciences) write about how these landslides may have formed. Some landslides on Mars seem to defy an important law of physics. "Long, runout landslides" are formed by huge volumes of rock and soil moving downslope, largely due to the force of gravity.

Space research at KU Leuven: missions that inspire big dreams
Space research at KU Leuven: missions that inspire big dreams
Let's first state the obvious: the universe is endlessly fascinating. When the first ever picture of a black hole was released this spring, it easily made front pages.

Imperial among UK institutions building parts for new £30m neutrino detector
Imperial among UK institutions building parts for new £30m neutrino detector
Researchers at Imperial are starting work on a huge new neutrino experiment, aiming to understand the origin and structure of the universe. The Deep Underground Neutrino Experiment (DUNE), to be assembled in the US, will have components designed and built by institutions across the UK, including Imperial.

Experiment to increase understanding of the universe secures £30m
UCL scientists working to understand neutrinos and antimatter through DUNE (the Deep Underground Neutrino Experiment) will benefit from the UK's latest multi-million pound investment in the project. The DUNE project brings together more than 1,000 physicists from the UK and 31 countries from Asia, Europe and the Americas to build the world's most advanced neutrino observatory, which could lead to profound changes in our understanding of the universe.

Cosmic explosions: detecting the highest-energy light
The most energetic form of light has been detected from a distant but powerful cosmic explosion known as a 'gamma-ray burst' for the first time, by an international team including UCL physicists using a UCL-built space telescope onboard NASA's Neil Gehrels Swift Observatory. The discovery and in particular, the unknown mechanisms that cause extremely high-energy light to be emitted in the afterglow of a gamma-ray burst (GRB).

Evidence of missing neutron star
The leftovers from a spectacular supernova that revolutionised our understanding of how stars end their lives have finally been spotted by astronomers at Cardiff University. The scientists claim to have found evidence of the location of a neutron star that was left behind when a massive star ended its life in a gigantic explosion, leading to a famous supernova dubbed Supernova 1987A.

A Runaway Star Ejected from the Galactic Heart of Darkness
Astronomers have spotted an ultrafast star, traveling at a blistering six million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The discovery of the star, known as S5-HVS1, was made by Carnegie Mellon University Assistant Professor of Physics Sergey Koposov as part of the Southern Stellar Stream Spectroscopic Survey (S5).

132 grams to communicate with Mars
On behalf of the ESA, UCLouvain has developed antennas for the LaRa instrument that will go to Mars in 2020 to study the red planet's habitability.

A bird in the nest and moving to Mars: News from the College
Here's a batch of fresh news and announcements from across Imperial. From bird-chick recognition, to Mars explorations, here is some quick-read news from across the College. A bird in the nest Passerine (or ‘perching') birds do not differentiate between the chicks in their nest - meaning they potentially raise chicks that aren't theirs, such as those that are the product of a cheating partner.

Particle detector for hunting dark matter installed a mile underground
Particle detector for hunting dark matter installed a mile underground
The central component of LUX-ZEPLIN (LZ) - the largest direct-detection dark matter experiment in the US - has been slowly lowered 4,850 feet down a shaft formerly used in gold-mining operations by a team involving UCL physicists. Although dark matter accounts for about 27 percent of the universe, we do not know what it is made of and experiments have yet to make direct contact with a particle - it has only been detected through its gravitational effects on normal matter.

Mapping the universe in extraordinary detail using UCL lenses
A three-dimensional map of the Universe that reaches deeper in space and time than ever before is one step closer as final testing begins on the Dark Energy Spectroscopic Instrument (DESI), designed and built in part by UCL physicists. From early 2020, DESI will observe the light from 35 million distant galaxies and 2.4 million quasars over five years to precisely map their distance from Earth and gauge how quickly they are moving away from us.

Hubble captures galaxies' ghostly gaze
Hubble captures galaxies’ ghostly gaze
When astronomers peer deep into space, they don't expect to find something staring back at them. In this new Hubble Space Telescope image, an uncanny pair of glowing eyes glares menacingly in our direction. The piercing "eyes” are the most prominent feature of what resembles the face of an otherworldly creature.
