Other projects like AgeGuess [8] focus on the senior demographics and enable the elderly to upload photos of themselves so the public can guess different ages. Lists of citizen science projects may change. For example, the Old Weather project website indicates that as of January 10, 2015, 51% of the logs were completed. [9]
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.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
The product of Simon Newcomb's J1900.0 mean tropical year of 31 556 925.9747 ephemeris seconds and a speed of light of 299 792.5 km/s produced a light-year of 9.460 530 × 10 15 m (rounded to the seven significant digits in the speed of light) found in several modern sources [10] [11] [12] was probably derived from an old source such as C. W ...
The first direct image of what the shape of a photon would look like is created. [467] [468] 15 November – Measles cases are reported to have surged across the world, with an estimated 10.3 million infections in 2023, a 20% increase from 2022. [469]
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.

The fair is fed by 28 regional science fairs, each of which is allocated a number of projects based on prior history of producing winning entries. The allocation in 2009 was 908 projects, an average of 24.7 projects per million population. [1] Awards are given in several categories at both junior (grades 6–8) and senior (grades 8–12) levels.
The International Year of Light and Light-based Technologies 2015 or International Year of Light 2015 (IYL 2015) was a United Nations observance that aimed to raise awareness of the achievements of light science and its applications, and its importance to humankind. IYL 2015 opening ceremonies was held on 19–20 January 2015 in Paris.
