What was the first constellation? What is the National Radio Astronomy Observatory? What is the Saptarishi constellation? What is a refracting telescope? What is a solar telescope? What are exoplanets? What type of constellation is Canis Minor?
When we add dwarf planets, asteroids, natural satellites, comets, Kuiper belt objects and the rest, the variety becomes truly amazing. Yet the solar system is just 1 of 400 now discovered planetary systems – most of which we already know to be quite different from our own neighbourhood....
Honing in on exoplanets To date, astronomers have identified more than 1000 confirmed exoplanets using NASA’s Kepler space telescope alone. This is around half of the 2000 that are known to exist. Its findings are thanks to the innovative “transit” method, which measuring how much a star's...
Many exoplanets are gas planets which orbit close to their stars. According to the Gemini Observatory, there are gas giants that cling to their stars. 9 It is not a case of size whether an object is a moon or a planet or an asteroid, the Moon Ganymede, which orbits around Jupiter is ...
So could it be that Earth really is unique? All living things on Earth are made of the same building blocks, long carbon-based molecules.所以地球真的是独一无二的吗？地球上所有的生物都有着相同的组成成分，即长碳基分子。Scientists now think that a large proportion of these molecules came from...
Retrievals of hazy planets (see e.g. Arney et al. 2016), as well as ocean worlds, might also help us further quantify the science potential of LIFE for a variety of different planet types. Another interesting study would be to increase S/N and R to even higher values. This will not ...
