planets
-
the stars and planets in the universe have different sizes and masses, but they are all spherical. so why are they all spherical and not any other shape?
-
from amazon to africa, wwf's report predicts catastrophic damage affecting 60% of trees and 50% of animals by the end of the century.
-
according to estimates by astronomers based on the assumption that each star has a planet orbiting, the universe has about 100,000 billion billion planets.
-
the beauty and mystery of our solar system are evident to anyone who has looked up at the night sky and marveled at the shining, distant stars.
-
every day the earth draws dozens of tons of dust from the universe but our green planet is getting lighter and lighter. why so?
-
all three planets revolve around a star called toi 270, located about 73 light-years from our earth.
-
the new google maps adds moon, mars and many other planets to enable us to 'fly' and spoiled for exploring 12 planets in the solar system after just a few clicks.
-
the planets start to heat up and can retain that hot temperature, even if they are far away from the host stars. so does life really exist in planets - can the area live?
-
with this finding, the official kepler-90 star system parallels our solar system in terms of the number of globules around a star.
-
when analyzing the data from the kepler spacecraft, astronomers discovered that 20 new planets have suitable conditions for survival and development.
-
nasa's kepler telescope recently discovered three new extrasolar planets orbiting a star called gj 9827 dubbed a 'super-earth'.
-
the length of the day in each planet depends on its distance to the sun, the orbital cycle (the time the planet orbits the sun) and the astronomical cycle (the time it spins around the axis).
-
every day, from the earth we see the sun from a distance of 149.6 million km, it looks like a giant glowing disk growing from the east. so if we stand on another planet in our solar system, what will the sun look like?
-
these are the strange sounds that nasa spacecraft get from jupiter, saturn, earth and the solar system edge.
-
so far, humans have discovered more than 400 extrasolar planets (exoplanets) in the universe. here are interesting facts about the most beautiful exoplanets that humans have ever known.
-
what if the plane we were so familiar with in each trip took off on other planets in the solar system, what would happen?
-
nasa has just announced the discovery of 7 planets of the same size and mass as the earth and together in a single star system - the trappist-1 star system 40 years away from us is probably the environment for live can exist.
-
this dwarf system (solar system 2.0) is about 39 light-years away from earth. how long does it take for nasa's space shuttle or new horizons spacecraft to get there?
-
let's admire the photos of 7 planets that can survive the life of the star system trappist-1 below!
-
there are many traits that can make a planet difficult to survive, a new study suggests that: for some planets, tilting orbits can be one of those factors.
