An international team of scientists discovers two potentially habitable planets orbiting a red dwarf star 137 light-years away. Continue reading Discovery of an Earth-size, potentially habitable planet
A recent study of the Small Magellanic Cloud has revealed that this nearby galaxy may actually be two galaxies that overlap from our point of view. Continue reading The Small Magellanic Cloud(s): nearby galaxy has a hidden twin
Astrophysicists have discovered a bizarre planet with clouds of sand over 200 light years away. Continue reading Welcome to the planet with clouds made of sand
Scientists have observed time dilation in the variability of quasars, an effect predicted by Einstein’s theory of relativity. Continue reading Einstein was right: testing the theory of relativity using quasars
Astronomers recently observed a planet being eaten by its star. In billions of years, the Earth will experience the same fate. Continue reading Astronomers Witness the End of a World
Temperature studies of rocks on Mars reveal water was briefly present in a part called Arabia Terra. Continue reading Arabia Terra on Mars Once Had Water — But Only Briefly
by Wei Lifigures by Catherine Ding The universe is massive, with an estimated 70 quintillion planets—that is 70 followed by an additional 18 zeros. In the Milky Way alone, where we reside, there are billions of planets. With these huge numbers, Earth seems very insignificant in the grand scheme of things. This raises the question: are we truly alone in this vast space of the … Continue reading Finding Life in Space: Why are we so special?
How do you introduce yourself, scientifically? I generally say that I’m an astronomer. More specifically, I’m an exoplanet astronomer, meaning I study planets that exist around other stars. In our solar system, all the planets orbit the Sun. I’m looking at planets in other stellar systems, orbiting stars much further away than the Sun. What are the implications or broader impacts of your work? This is … Continue reading What Does an Astronomer Do?
Jupiter’s moon Europa might not need the sun’s rays to glow. If so, its color will shed light on the chemistry of the ocean world. Continue reading Europa’s Glowing Ice Could Shine Light on the Moon’s Subterranean Secrets
A team of international astronomers have identified the smallest free-floating “rogue” planet observed to date. Continue reading Going Rogue in Space
