Houston, we… are not in Kansas anymore. “The Wizard of Oz” and space exploration are two topics that by all rights should have nothing in common. But with the 1939 film celebrating its 85th anniversary and “Wicked” landing like a twister-thrown farmhouse into movie theaters this week, we are clicking our heels three times to […]
Something evil may be lurking in a black hole in Adam Roberts’s new novel Liuzishan/Getty Images Lake of DarknessAdam Roberts (Gollancz) I WAS recently asked for my definition of “hard science fiction” and I burbled something along the lines of “it has to have a lot of science in it, and also spaceships”. I’m not […]
An artist’s depiction of a system showing its host star, transiting planet and misaligned protoplanetary disc NASA/JPL-Caltech/R. Hurt, K. Miller (Caltech/IPAC) A world seen orbiting a 3-million-year-old star about 520 light years from Earth is one of the youngest known planets, offering a window into early planet formation. The star is an early-stage dwarf star, […]
Artistic illustration of an ice-covered river sourced from meltwater beneath Mars’s south polar cap. Peter Buhler / PSI Mars is a frozen desert world, enshrouded in a thin atmosphere of carbon dioxide. This atmosphere is so wispy, the pressure is less than 1% that of Earth’s air at sea level — too rarefied to enable […]

The sun’s upper atmosphere, or corona, in ultraviolet light ESA & NASA/Solar Orbiter/EUI Team These fiery images are the clearest views we have ever had of the sun, taken by the Solar Orbiter spacecraft. Solar Orbiter, a joint mission between the European Space Agency (ESA) and NASA, is the most advanced instrument to orbit the […]
There is a lot to keep track of when working in space NASA via Getty Image Astronauts aboard the International Space Station (ISS) had slower memory, attention and processing speed after six months, raising concerns about the impact of cognitive impairment on future space missions to Mars. The extreme environment of space, with reduced gravity, […]

Sparks Albert Einstein’s theory of general relativity has been proven right on the largest scale yet. An analysis of millions of galaxies shows that the way they have evolved and clustered over billions of years is consistent with […]
General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of cosmic evolution collected by the Dark Energy Spectroscopic Instrument, or DESI. Albert Einstein’s 1915 theory, general relativity, has remained humanity’s best description of gravity for the past 100 years. Cosmologists have used general relativity to […]
