And it’s about to go faster.

Lead study author Charles Cadieux, a PhD student at the University of Montreal, remarked that among all known temperate exoplanets, LHS 1,140 b is possibly the most promising candidate for confirming liquid water on the surface of an alien world.

Approximately 10 to 20 percent of the exoplanet’s mass is estimated to be water. In stark contrast, Earth’s oceans account for a mere 0.02 percent of its mass. The state of this water, whether liquid or ice, hinges on the planet’s atmospheric composition, with gases like carbon dioxide playing a crucial role.

One encouraging factor is the planet’s gentle warming by its red dwarf star, which is only one-fifth the size of our Sun. This stellar relationship suggests that the exoplanet’s surface temperature is likely comparable to that of Earth and Mars.

Producing fast-moving ‘fireballs’ in the lab could shed light on processes in extreme astrophysical emissions.

Since the Apollo missions over half a century ago, scientists have suspected that the lunar surface is riddled with an extensive network of tunnels.

But despite our best efforts, they’ve been unable to once and for all confirm their existence — until now.

Scientists at the University of Trento in Italy have used cutting-edge data analysis tools to examine radar reflections to provide the “first direct evidence of an accessible lava tube under the surface of the Moon,” according to University of Trento professor Lorenzo Bruzzone, coauthor of a new paper published in the journal Nature Astronomy.

In this study, we explore the accelerated expansion of the universe within the framework of modified f(Q) gravity. The investigation focus on the role of bulk viscosity in understanding the universe’s accelerated expansion. Specifically, a bulk viscous matter-dominated cosmological model is considered, with the bulk viscosity coefficient expressed as $$\zeta = \zeta _0 \rho H^{-1} + \zeta _1 H $$ ζ = ζ 0 ρ H — 1 + ζ 1 H. We consider the power law f(Q) function $$f(Q)=\alpha Q^n $$ f (Q ) = α Q n, where $$\alpha $$ α and n are arbitrary constants and derive the analytical solutions for the field equations corresponding to a flat FLRW metric. Subsequently, we used the combined Cosmic Chronometers (CC)+Pantheon+SH0ES sample to estimate the free parameters of the obtained analytic solution.

When listen to void of space, we hear no alien signals, but could the galaxy be quiet because ancient empires slumber inside it?

Scientists at the European Space Agency have designed and 3D printed bricks that are similar to LEGO pieces and are made out of 4.5-billion-year-old meteorite dust. The pieces, called ESA Space Bricks, are part of an initiative to develop clean and sustainable buildings on the Moon that lunar settlers could live and work in. In theory, astronauts could use materials readily available on the lunar surface to build structures, launch pads, and other vital pieces of infrastructure without having to solely rely on Earth-made supplies.

But why did the scientists end up going with the LEGO-inspired design for their ESA Space Bricks? While the bricks are not currently intended to be used to construct anything on the Moon, their existence does prove to researchers that it is possible to 3D print durable interlocking building bricks out of lunar materials.

“Nobody has built a structure on the Moon, so it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks,” says ESA Science Officer Aidan Cowley. “It was both fun and useful in scientifically understanding the boundaries of these techniques.”

Scientists discover that interplanetary shocks that strike Earth’s magnetic field head-on cause more powerful ground-level electric currents, threatening pipelines and submarine cables.

Auroras are caused by particles from the sun hitting the Earth’s magnetic field — but these impacts also cause geomagnetically induced currents at ground level, which can damage infrastructure that conducts electricity. Scientists studying these currents to protect critical infrastructure have carried out the first research which compares interplanetary shocks to real-time measurements of geomagnetically induced currents, showing that the angle of the shocks’ impact is key for forecasting possible damage to infrastructure: shocks that hit the magnetic field at an angle produce less powerful currents.
