The cool white dwarf WDJ1330+6435 has accreted sodium-rich rocky material from its planetary system into its atmosphere. The immense atmospheric density causes the sodium to absorb light over broad range of yellow, orange, and red wavelengths, giving the WDJ1330+6435 a ghostly green…
When we look across the Universe, we might come to the conclusion that intelligent life is really a very rare thing indeed For as long as humanity has looked up at the stars, we have wondered whether someone, somewhere, might…
Scientists have discovered a powerful new way to decode the weather on distant worlds, revealing surprisingly organized patterns hidden within the turbulent atmosphere of a mysterious object 20 light-years from Earth. Researchers at Trinity College Dublin used observations from NASA's James…
RNZ / News / World Astronomers analyzing white dwarf stars have for the first time found a star that would appear green to human eyes, according to a new study. While for most stars, colour is temperature-dependent and limited to a few…
The findings were reported in research published in the journal RAS Techniques and Instruments. The study, led by astrophysicist Mark Hollands of the University of Warwick, examined the spectra and atmospheric properties of 151 white dwarfs to investigate how their light…
Just in time for Halloween, astronomers have identified a star with an unusual yellowish-green glow, challenging what scientists know about the colours of stars. Named WD J1330+6435, the object is a white dwarf located about 280 light-years from Earth in the constellation…
Every piece of equipment that comes our way, whether a camera, a lens or an accessory, gets the same level of careful scrutiny. We discover what products are good at and what they are not so you don’t have to.
Astronomers discovered that WASP-17b has an uneven atmosphere, with extreme temperature differences between its morning and evening sides. Planets appear as perfectly round disks when they cross in front of their stars, and astronomers have long measured them that way.
Planets can orbit their stars so closely that their atmospheres are stripped away. Even more surprisingly, some might survive inside the outer layers of a star … How Close Can a Planet Get to Its Star? Planets can orbit their stars…
New Delhi: Earth is the only known planet to support life, but it may not be the ideal place for life to thrive. Scientists are exploring whether some planets beyond our solar system could offer conditions even more favourable to…
