New observations show that small planets may be more widespread in our galaxy than previously thought.
Building a terrestrial planet requires raw materials that weren't available in the early history of the universe.
Unfortunately, stars don't have birth certificates. So, astronomers have a tough time figuring out their ages. Knowing a star's age is critical for understanding how our Milky Way galaxy built itself up over billions of years from smaller galaxies.
Baby galaxies from the young Universe more than 12 billion years ago evolved faster than previously thought, shows new research from the Niels Bohr Institute.
Researchers working at the University of Bonn in Germany have used computer simulations to discover the first evidence that the way in which stars form depends upon the conditions of their birth environments.
It’s very difficult to kick a star out of the galaxy. In fact, the primary mechanism that astronomers have come up with that can give a star the two-million-plus mile-per-hour kick it takes requires a close encounter with the supermassive black hole at the galaxy’s core.
Low in the south in the summer sky shines the constellation Scorpius and the bright, red supergiant star Antares. Many of the brightest stars in Scorpius, and hundreds of its fainter stars, are among the youngest stars found near the earth, and a new analysis of them may result in a rethinking of both their ages and the ages of other groups of stars.
Three astronomers at the University of Toronto have found the most numerous batch of young, supermassive stars yet observed in our galaxy: hundreds of thousands of stars, including several hundreds of the most massive kind --blue stars dozens of times heavier than our Sun.
The Milky Way galaxy continues to devour its small neighboring dwarf galaxies and the evidence is spread out across the sky.
