There is a state of relaxation that few of us spend much time in, but which comes with profound well-being benefits. With healthier ageing, reduced risk of disease and feeling more energised all on offer, here's how to get there

Some of the world's most advanced robots showed off their skills at tech shows and sporting events, doing everything from cooking shrimp to running half marathons

The highlights of spaceflight in 2025 have included missions to explore the Moon, Mars, and the Sun — and more is coming in the New Year.

The post Spaceflight for Astronomy — A Look Back and Ahead appeared first on Sky & Telescope.

The Linac Coherent Light Source in California has been firing record-breaking X-ray pulses for years, but now it’s due for a shutdown and an upgrade. When it is turned back on, it will be even more powerful

The proposed Russian Orbital Station will stick to a familiar path instead of an ambitious polar orbit

From immune cell therapies to measles outbreaks to federal attacks on public health, these are some of the health topics we’ll be watching next year

The Majorana 1 quantum computer was hailed as a significant breakthrough by Microsoft, but critics say the company has yet to prove it actually works despite a year of debate

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been used to show this activity is mostly random noise

A joint research team from South Korea has developed a fascinating wheel inspired by origami and Da Vinci bridge principles that could unlock access to the Moon’s most dangerous and scientifically useful terrain. The wheel expands from 230 mm to 500 mm in diameter on demand, allowing small rovers to navigate steep lunar pits and lava tube entrances that would trap conventional vehicles.

Astronomers using the Hubble Space Telescope have discovered the largest planet forming disk ever observed around a young star, stretching nearly 40 times the diameter of our Solar System. Nicknamed “Dracula’s Chivito” for its hamburger like appearance when viewed edge on, this massive disk reveals an unexpectedly chaotic and asymmetric structure with wisps of material extending far above and below its central plane. The discovery offers an unprecedented window into how planets might form in extreme environments, challenging previous assumptions about the orderly nature of planetary nurseries.

Three start-ups are aiming to create gene-edited babies. Columnist Michael Le Page has no doubt that editing our offspring will one day become routine, but not like this

Yesterday the Sun reached its southernmost point in planet Earth's sky.

At the end of their lives, most satellites fall to their death. Many of the smaller ones, including most of those going up as part of the “mega-constellations” currently under construction, are intended to burn up in the atmosphere. This Design for Demise (D4D) principle has unintended consequences, according to a paper by Antoinette Ott and Christophe Bonnal, both of whom work for MaiaSpace, a company designing reusable launch vehicles for the small satellite market.

Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. This map will enable 3D distance measurements to other galaxies and allow astronomers to measure the influence of Cosmic Inflation on the large-scale structure of the Universe.
