Planets orbiting close to hot stars experience intense extreme-ultraviolet radiation, potentially leading to atmosphere evaporation and to thermal dissociation of molecules. However, this extreme regime remains mainly unexplored due to observational challenges. Only a single known ultra-hot giant planet, KE...
Accordingly, Cuntz and colleagues see no reason why life would not have a sufficient "window of opportunity" to arise on worlds bathed in an F-type star's light. "The lifetimes of F-type stars on the main-sequence appear to be sufficiently long for life having a chance to start and to...
Suppose the angular separation of two stars is smaller than the angular resolution of your eyes. How will the stars appear to your eyes? Why can't a white dwarf have a mass greater than 1.4M? Compared with power input, the power output of an ide...
There’s Still Unknown Physics in Our Universe This Test Could Prove If Universe Is Made for Life A Father-Daughter Duo Cracked an ‘Alien’ Code This Molecule May Be the Source of Life on Earth Neutron Stars Could Be Nurseries for Axions ...
Spintronics is expected to be one of the next revolutions in computing. The idea is to fabricate devices that operate using not just an electron’s charge, but also its spin. Because the spin of an electron can be switched more quickly than charge can be moved round, these spintronic device...
With this new understanding, the researchers could estimate a range of initial temperatures for which the effect emerges and determine how different the initial values of this parameter must be in order for the Mpemba effect to appear. The results also support predictions of the existence of an ...
