Is space infinite? We asked 5 experts - Universal-Sci
WEBAug 14, 2021 · We’ve known for some time now our universe is expanding, and in recent years discovered this was happening considerably faster than we’d expected. Yet despite momentous innovations in telescope and satellite technology, it’s thought much of what’s out there in the cosmos lies beyond our line of sight …
Nuclear fusion: building a star on Earth is hard, which is why we …
WEBMar 7, 2021 · The challenges. Despite the huge advances in the field of materials for fusion, there’s still a lot of work that needs to be done. The main issue is we rely on several proxy experiments to recreate potential reactor conditions, and have to try and stitch this data together, often using very small samples.
How do astronomers know the age of the planets and stars?
WEBOct 11, 2023 · A star’s spin also generates a strong magnetic field and produces magnetic activity, such as stellar flares – powerful bursts of energy and light that occur on stars’ surfaces. A steady decline in magnetic activity from a star can also help estimate its age.
How big is the universe?
WEBJul 8, 2023 · How far away is the moon? Perhaps the distance to our Moon is easiest to describe; after all, it is the closest celestial body to Earth. The actual distance between Earth and the Moon varies throughout the Moon's orbit, but the Moon's average distance is approximately 384,402 kilometers.. A distance of 380,000 kilometers is on the edge of being conceivable on a human scale.
What is the driving force behind odd radio circles? - Universal-Sci
WEBJan 8, 2024 · Astronomers are usually familiar with stars, planets, black holes, and galaxies. But in 2019, something new caught their attention. The ASKAP telescope in Australia detected mysterious circles in space, each large enough to encircle whole galaxies.

WEBIn a recent cosmic event that sounds more like science fiction than reality, astronomers reported the sighting of two ice giant exoplanets (planets outside our solar system) crashing into each other around a star similar to our sun.
Shape of the universe: could it be curved, not flat?
WEBNov 14, 2019 · By Eleonora Di Valentino - Postdoctoral Researcher of Astrophysics, University of Manchester. No matter how elegant your theory is, experimental data will have the last word. Observations of the retrograde motion of the planets were fundamental to the Copernican revolution, in which the sun replaced Earth at the centre of the solar system.
Explainer: what is the Great Attractor and its pull on our galaxy?
WEBMay 31, 2016 · Around four decades ago, astronomers became aware that our galaxy, the Milky Way, was moving through space at a much faster rate than expected. At 2.2-million kilometres an hour, the speed of the Milky Way through the Cosmos is 2,500 times faster than a cruising airliner; 55 times more than the esca

WEBDec 17, 2019 · Unlike protons, electrons and positrons are indivisible – so we’ll know exactly what we’re colliding. We’ll also be able to vary the energy at which the two collide, to produce specific antimatter particles, and measure their properties – particularly the way they decay – much more accurately.
