Nature publication IceCube in Antarctica proves 60-year-old physics prediction with high-energy particle from the Universe
In 1960, Nobel Prize winner Sheldon Glashow predicted a process within the Standard Model, the most important model of particle physics. The theory describes the interaction of an antineutrino with an electron producing a new particle. However, no particle accelerator on Earth, not even the Large Hadron Collider at CERN, is able to make this process happen because it requires extremely high particle energy.

Astronomers capture stellar winds in unprecedented detail
Astronomers capture stellar winds in unprecedented detail
Astronomers present an explanation for the mesmerising shapes of planetary nebulae. The discovery is based on an extraordinary set of observations of stellar winds around ageing stars. Contrary to common consensus, the team found that stellar winds are not spherical but have a shape similar to that of planetary nebulae.

KU Leuven researchers shed new light on solar flares
KU Leuven researchers shed new light on solar flares
Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new combination of physical models. Solar flares are explosions on the surface of the Sun that release an enormous amount of energy, equivalent to a trillion 'Little Boy' atomic bombs exploding at the same time.

University of Louvain and European Space Agency join forces to screen COVID-19
Objective: increase COVID-19 screening capacity throughout Europe via a mobile, fast and flexible method First phase: Piedmont, Italy , to screen front-line teams (medical, volunteer, police, civil protection) The University of Louvain (UCLouvain ) and the European Space Agency (ESA ) are joining forces to deploy a mobile laboratory capable of testing front-line screening teams : doctors, nurses, volunteers, police, civil protection actors.

Astronomers capture rare images of planet-forming disks around stars
Astronomers capture rare images of planet-forming disks around stars
An international team of astronomers has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away. These disks of dust and gas, similar in shape to a music record, form around young stars. The images shed new light on how planetary systems are formed. They were published in the journal Astronomy & Astrophysics .

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.

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.

KU Leuven researchers use satellite data to calculate snow depth in mountain ranges
Bioscience engineers at KU Leuven have developed a method to measure the snow depth in all mountain ranges in the Northern Hemisphere using satellites. This technique makes it possible to study areas that cannot be accessed for local measurements, such as the Himalayas. The findings were published .

Blue supergiant stars open doors to concert in space
Blue supergiants are rock 'n' roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our knowledge of these stars was limited. Using recent NASA space telescope data, an international team led by KU Leuven studied the sounds originating inside these stars and discovered that almost all blue supergiants shimmer in brightness because of waves on their surface.

Stellar wind of old stars reveals existence of a partner
Red giants are old stars that eject gaseous material and solid particles through a stellar wind. Some red giants appeared to lose an exceptionally large amount of mass this way. However, new observations reveal that this is not quite the case. The stellar wind is not more intense than normal, but is affected by a partner that was overlooked until now: a second star that circles the red giant.

IceCube neutrinos point to long-sought cosmic ray accelerator
Ghost particle originates from supermassive black hole An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos. The measured neutrino originates from a supermassive black hole. Researchers from VUB are among those behind the sensational finding.

Stephen Hawking and Thomas Hertog propose a new cosmological theory
Stephen Hawking's last paper, co-authored by Thomas Hertog, does away with the infinite multiverse and predicts a simpler and finite universe. Find out more in this ERC interview with Thomas Hertog.  You put forward a new theory of the origin of the universe. What's wrong with the current one? "The prevailing theory of the Big Bang is called eternal inflation.

What have we learned about TRAPPIST-1 during this last year?
Just a year ago, on the 22 February 2017, at a press conference at NASA headquarters, an international team of researchers revealed the existence of a unique exoplanetary system, made up of seven planets orbiting a small nearby star. Known as TRAPPIST-1, this system created a hug buzz on the Web, in the media, and within the scientific community.

Journey to the Center of a White-Dwarf Star
Journey to the Center of a White-Dwarf Star
A stellar core that challenges predictions: here is the result of the first cartography of the interior of a white-dwarf star performed by an international team that includes  Valérie Van Grootel and Marc-Antoine Dupret , two researchers belonging to the STAR Institute at Université de Liège.  This discovery will provide insights on the different physical mechanisms involved in the evolution of stars and our Sun.
