Dewdrops on a spiderweb reveal the physics behind cell structures

As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon ...

Fornax A galaxy investigated with AstroSat

Using the AstroSat spacecraft, Indian astronomers have performed an imaging and spectroscopic study of the Fornax A galaxy. Results of the study, published January 13 on the arXiv preprint server, provide more clues on the ...

Comb of a lifetime: A new method for fluorescence microscopy

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific ...

A Rosetta stone for planet formation

Planets are formed from the disk of gas and dust around a star, but the mechanisms for doing so are imperfectly understood. Gas is the key driver in the dynamical evolution of planets, for example, because it is the dominant ...

James Webb Telescope will reveal hidden galaxies

Two new studies from the University of Melbourne will help the largest, most powerful and complex space telescope ever built to uncover galaxies never before seen by humanity.

How planetary nebulae get their shapes

About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most of that helium into carbon and oxygen. It will have swollen to a size large enough to ...
