Astronomers using TESS report the discovery of Gliese 12 b, a Venus-sized exoplanet located 40 light-years away, with an equilibrium temperature of 315 K (42 °C; 107 °F). This makes it the nearest, transiting, temperate, Earth-sized world located to date.
For example, the light-second, useful in astronomy, telecommunications and relativistic physics, is exactly 299 792 458 metres or 1 / 31 557 600 of a light-year. Units such as the light-minute, light-hour and light-day are sometimes used in popular science publications.
List of student science award programs - a generic list of programs, fairs, and/or competitions for youth or students. Some examples include the Intel International Science and Engineering Fair or European Union Contest for Young Scientists , India International Sarabhai Student Scientist Award.
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
The first aurora beyond the Solar System is reported, on a brown dwarf 18 light years from Earth. [323] Astronomers report the discovery of HD 219134 b, a rocky exoplanet, due to its size of 1.6 Earth and density of 6 g/cm 3, that is the closest such exoplanet to Earth, at 21.25 light-years away.

A list of future observable astronomical events. [1] These are by no means all events, but only the notable or rare ones. In particular, it does not include solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these).
But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same phenomenon can also sometimes make skies ...
Multiple other interstellar clouds exist in the region within 300 light-years of the Sun, known as the Local Bubble. [262] The latter feature is an hourglass-shaped cavity or superbubble in the interstellar medium roughly 300 light-years across. The bubble is suffused with high-temperature plasma, suggesting that it may be the product of ...
