Scientists Use ISS Pictures to Map Light Pollution

Researchers belonging to the Cities at Night project have obtained nighttime images of cities from the International Space Station (ISS) in order to gauge the light pollution globally. The new study that was released on Tuesday at IAU XXIX General Assembly in Hawaii, established that the diffuse glow that is witnessed from space is nothing, but dispersed light from streetlights ...

Stars Produce Sound, Even Bats, Dolphins Struggle to Hear: Reveal Scientists

  A team of researchers from University of York and Mumbai-based TIFR found evidence that stars may generate sound, in a chance discovery. The study of fluids in motion or hydrodynamics dates back to the Egyptians but while examining the interaction of an ultra-intense laser with a plasma target, the team observed something unexpected. Scientist John Pasley, of the York ...

Japan’s Hitachi develops world’s most powerful microscope

Japan MNC Hitachi has developed a microscope with capacity of highest known resolution based on the transmission of electrons to observe at the atomic level, which may revolutionize the way we see atoms. The transmission electron microscope (TEM), work on which was started in 2010, was completed this week and has a 43-picometre resolution (a picometre is one-trillionth of a ...

Reionization maps show stars are younger than thought

New maps of cosmic background radiation have helped scientists realize that the “reionization” process could be more recent than estimated until now. Reionization, a key process in cosmology, is associated with star formation, which cosmologists date back to after the “dark ages” of the Universe, when there was still no starlight. The NASA WMAP satellite, launched in 2001, had given ...

Exoplanets Likely to Have Water, Hospitable to Life

A recent study shows that planets outside our solar system, exoplanets, are expected to have liquid and be more habitable than previously thought. “Planets with potential oceans could have a climate that is much more similar to Earth’s than previously expected,” said Jeremy Leconte, post-doctoral fellow at the Canadian Institute for Theoretical Astrophysics (CITA) at University of Toronto. The study ...
