A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered ablack holelying just 1000 light-years from Earth. The black hole is closer to our Solar System than any ot
Scientists say they discovered an earth-like planet orbiting the star closest to our planet other than the sun. It is the closest planet ever found outside our solar system that could support life as we know it. This planet is just 4.2 light years away from us. It is so close that spa...

The Sun is the hub of a huge rotating system consisting of nine planets, their satellites, and numerous small bodies, including asteroids, comets, and meteoroids. An estimated 99.85 percent of the mass of our solar system is contained within the Sun, while the planets collectively make up mos...
to a cluster of massive young stars, called the Trapezium Cluster, emitting intense ultraviolet radiation, capable of shaping clouds of dust and gas. Understanding how this phenomenon influences the environment is a key question for studying the formation of star systems like our own solar system...
This is the closest known encounter of a star to our solar system with a well-constrained distance and velocity. Previous work suggests that flybys within 0.25 pc occur infrequently ($\\\sim$0.1 Myr$^{-1}$). We show that given the low mass and high velocity of the binary system, the...
Scientists say they discovered an earth-like planet or-biting the star closest to our planet other than the sun. It is the closest planet ever found outside our solar system that could support life as we know it. This planet is just4. 2 light years away from us. It is so close that...
阅读理解。Mercury(水星) is the closest planet to the sun. It doesn't have air. 1 It is a small planet. Mercury is about one-third the size of the Earth. If the earth was the size of a baseball,Mercury would be the size of a golf ball(高尔夫球). Because it is so small, ...
NASA’s James Webb Space Telescope has observed a distant planet outside our solar system – and unlike anything in it – to reveal what is likely a highly reflective world with a steamy atmosphere. It’s the closest look yet at the mysterious world, a “mini-Neptune” that was l...
“It’s monumental to be able to get a spacecraft this close to the Sun,” said John Wirzburger, the Parker Solar Probe mission systems engineer at APL. “This is a challenge the space science community has wanted to tackle since 1958 and had spent decades advancing the technology ...
