Satellite streaks are a blight on astronomy. How much are observations by the Vera Rubin super telescope going to suffer from this contamination?

Scientists have used the James Webb Space Telescope (JWST) to make a groundbreaking discovery about water in space, detecting a special type of water ice around a young star that could help explain how water travels from stellar nurseries to planets and comets.
Scientists are revolutionising the search for extraterrestrial life by challenging our somewhat Earth-centric assumptions about where and how life might exist in the universe. A new review argues that we must embrace the remarkable diversity of exoplanets discovered over the past two decades and consider a much broader range of environments that could potentially host life.
Supermassive black holes that seem too large to exist in the early universe may have grown from primordial black holes formed in the first second after the Big Bang.
The surprise display was captured on June 9 by aurora chaser Harlan Thomas.
In 1912, astronomer Victor Hess discovered strange, high-energy particles known as "cosmic rays." Since then, researchers have hunted for their birthplaces. Today, we know about some of the cosmic ray "launch pads", ranging from the Sun and supernova explosions to black holes and distant active galactic nuclei. What astronomers are now searching for are sources of cosmic rays within the Milky Way Galaxy.
Extended periods in space can lead to all kinds of health problems. The hazard posed by radiation is well known and is the reason NASA and other space agencies impose limits on the amount astronauts are exposed to. There's also microgravity, which has been studied extensively thanks to regular missions to the International Space Station and long-term studies (like the NASA Twins Study). According to this research, extended periods in microgravity will result in muscle atrophy, bone density loss, changes in eyesight, effects on the cardiovascular and endocrine systems, and even genetic changes.
If our Solar System seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the Moon moves through light and shadow, and the Sun hangs in the sky. But in reality, everything is moving and influencing everything else, and the fine balance we observe can easily be disrupted. Could passing stars have disrupted Earth's orbit and ushered in dramatic climatic changes in our planet's past?

Staff at the European Southern Observatory have a system to clean the La Silla Observatory's delicate mirrors without breaking them.
Using NASA's Chandra X-ray space telescope, astronomers have discovered an entire galaxy cluster wrapped in a 20 million light-year-wide envelope of charged particles.
The beads are over 3.3 billion years old, and date from the formation of the "Man in the Moon."
