Big Bang Conditions Created in Lab.

By smashing gold particles together at super-fast speeds, physicists have basically melted protons, creating a kind of "quark soup" of matter that is about 250,000 times hotter than the center of the sun and similar to conditions just after the birth of the universe.

Maths problem solved after stumping the world for nearly a century


University of California (UC) San Diego mathematicians Jacques Verstraete and Sam Mattheus have solved a puzzling Ramsey theory problem that's had little progress since the great Paul Erdös made some breakthroughs in 1937.
Fittingly, the rather complex Ramsey theory – a branch of the numbers game concerned with order within structures, named after British mathematician and philosopher Frank P. Ramsey – is most often described in the context of a party. The best known problem in this graph-theory corner of mathematics, r(3,3), often called the theorem on friends and strangers, supposes that in a group of six people, you’ll find at least three people who all know each other or three who all don’t know each other. The answer to r(3,3), apparently, is six.

NASA’s Mars Fleet Will Still Conduct Science While Lying Low


NASA will hold off sending commands to its Mars fleet for two weeks, from Nov. 11 to 25, while Earth and the Red Planet are on opposite sides of the Sun. Called Mars solar conjunction, this phenomenon happens every two years. The missions pause because hot, ionized gas expelled from the Sun’s corona could potentially corrupt radio signals sent from Earth to NASA’s Mars spacecraft, leading to unexpected behaviors.

Huge explosions 100 billion times the energy of the Sun stump scientists


Astronomers have been left shaking their heads at the strikingly unusual behavior of the Tasmanian Devil, or AT2022tsd, a luminous fast blue optical transient (LFBOT) located around a billion light-years from Earth. It not only defied the usual ‘live fast die young’ nature of LFBOTs by repeatedly exploding over months, but was throwing out energy flares hundreds of billions times that of stars like the Sun.

As the ISS turns 25, a look back at the space laboratory's legacy


Hurtling through space at 17,500 miles per hour, the International Space Station (ISS) circles the entire globe roughly once every 90 minutes — which amounts to 16 sunrises and sunsets every 24 hours. At any point in time, the station is home to no less than seven international crew members, with the station's living and working areas amounting to the size of an average six-bedroom house.

Mission to travel to Mars and survey the red planet’s two moons; Phobos and Deimos.

The Martian Moons eXploration (MMX) mission is a project to explore the two moons of Mars, with a planned launch in the mid-2020s. Approximately one year after leaving Earth, the spacecraft will arrive in Martian space and enter into an orbit around Mars. It will then move into a Quasi Satellite Orbit (QSO) around the Martian moon, Phobos, to collect scientific data and gather a sample from the moon’s surface.
