The most striking science photos of the week: including the Perseid meteor shower and glowing underwater wonders. Record warm seas have brought an extraordinary range of new species to UK waters. Britain’s seas have had their warmest start to the year since records began, with BBC analysis finding that the average sea temperature from January to the end of July …

A black hole’s bizarre “heartbeat” is forcing astronomers to reconsider how these cosmic heavyweights behave. Observations of IGR J17091-3624 — a black hole in a binary system roughly 28,000 light-years from Earth — were taken using NASA’s Imaging X-ray Polarimetry Explorer (IXPE). Nicknamed the “heartbeat” black hole for its dramatic, rhythmic pulses in brightness, the object feeds on matter stolen …

The mission carries the most sophisticated radar systems ever launched as part of a NASA mission. In a first, the satellite combines two synthetic aperture radar (SAR) systems: an L-band system that can see through clouds and forest canopy, and an S-band system that can see through clouds as well but is more sensitive to light vegetation and moisture in …

If humans ever leave Earth to colonize other planets, they will need companions that are incredibly resilient and able to shrug off the lethal conditions found in outer space. Tiny animals called tardigrades, only visible under magnification, are perfect for the job. At about 0.004 inches long, a tardigrade can nap through a blast of ionizing radiation strong enough to …

Topline The moon will this Saturday, Aug. 17, join a “planet parade” building in the morning sky. As it does so, it will brush past the Pleiades, a sparkling open cluster of stars that’s best known for dominating the winter night sky. Best seen about an hour before sunrise, bright planets Venus and Jupiter will continue to dominate in the …

NASA is asking six companies to help the agency move spacecraft between difficult-to-reach orbits. The agency recently awarded a total of $1.4 million to the group, which includes companies like Blue Origin, United Launch Alliance and Rocket Lab. The goal is to eventually send various sizes and types of spacecraft to a variety of destinations in the final frontier, using …

A groundbreaking discovery has reshaped our perception of how fast galaxies evolved in the early universe. Astronomers have detected oxygen in the light from the galaxy JADES-GS-z14-0, the most distant known galaxy to date. This observation, published in Astronomy & Astrophysics, reveals that complex chemical enrichment was already underway just 300 million years after the Big Bang. The galaxy’s light …

For the first time, scientists have captured a real-time view of a human embryo implanting in a laboratory model of a uterus. Being able to witness the complex implantation process may be helpful for advancing fertility procedures, such as in vitro fertilization (IVF), the researchers say. “We have observed that human embryos burrow into the uterus, exerting considerable force during …
