Is Uranus Losing Its Atmosphere?
Mars was once covered by oceans, but lost its atmosphere over time, according to Gina DiBraccio, a space physicist at NASA’s Goddard Space Flight Center and project scientist for the Mars Atmosphere and Volatile Evolution, or MAVEN mission. Is the same thing happening to Uranus? The magnetic bubble surrounding the giant gas planet may be siphoning its atmosphere off into space,…
We’ve figured out why bubbles make a ‘pop’ sound when they burst
A number of difference forces are involved in producing sound when a bubble pops, and the exact noise depends on the chemical properties of the soap film Source: https://www.newscientist.com/article/2238125-weve-figured-out-why-bubbles-make-a-pop-sound-when-they-burst/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Watch tadpoles breathe by sucking in air bubbles at water’s surface
Most tadpoles breathe air but they are too weak to break the elastic “skin” on top of ponds created by water tension – so they suck air bubbles from the surface Source: https://www.newscientist.com/article/2234062-watch-tadpoles-breathe-by-sucking-in-air-bubbles-at-waters-surface/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Driving massive galaxy outflows with supermassive blackholes
Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material onto their hot circumnuclear disks, releasing the energy in bursts of radiation or as particle jets moving at close to the speed of light. These energetic outbursts in turn drive outflows of ionized, neutral, and molecular gas that can extend over thousands of light-years…
Are solar storms dangerous to us?
Activity on the sun affects Earth’s magnetic field. It can cause geomagnetic storms, the same events that create the beautiful aurorae, or northern and southern lights. Are these storms dangerous? Source: https://earthsky.org/space/are-solar-storms-dangerous-to-us…

Nightside barrier gently brakes ‘bursty’ plasma bubbles
The solar wind that pummels the Earth’s dayside magnetosphere causes turbulence, like air over a wing. Physicists at Rice University have developed new methods to characterize how that influences space weather on the nightside.

Does tapping a beer can prevent it foaming over? Scientists found out
A rigorous randomised trial has put to bed the idea that tapping or flicking a can of beer makes bubbles come to the top and prevents the liquid fizzing out Source: https://www.newscientist.com/article/2226735-does-tapping-a-beer-can-prevent-it-foaming-over-scientists-found-out/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
