The 'mirrors' exist for only a fragment of time but could help to reduce the size of ultra-high power lasers, which currently occupy buildings the size of aircraft hangars, to university basement sizes.
They have potential to be developed into a variety of plasma-based, high damage-threshold optical elements that could lead to small footprint, ultra-high-power, ultra-short pulse laser syst

A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this most famous of liquids.

While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material's own natural frequency can send its vibrations into overdrive, causing the glass to shatter.

Mars clouds are very much like Earth's cirrus clouds but thinner. While Earth clouds can contain liquid water, the low temperatures and pressures on Mars only allow for water-ice (and CO2 ice) clouds to form. However, these water-ice clouds are optically thin because of the low amounts of water present in the Martian atmosphere; if all the water were on the surface, it would make a layer thinner

A team of astronomers led by MPIA scientist Diana Kossakowski have discovered an Earth-mass exoplanet orbiting in the habitable zone of the red dwarf star Wolf 1069. Although the rotation of this planet, named Wolf 1069 b, is probably tidally locked to its path around the parent star, the team is optimistic it may provide durable habitable conditions across a wide area of its dayside.

Experiments to complete scientific understanding of how reduced gravity affects boiling and condensation
Friday, 03 February 2023 18:18
With temperatures on the moon ranging from minus 410 to a scorching 250 degrees Fahrenheit, it's an understatement to say that humans will need habitats with heat and air conditioning to survive there long term.
But heating and cooling systems won't be effective enough to support habitats for lunar exploration or even longer trips to Mars without an understanding of what reduced gravity does to boiling and condensation.
