Japanese scientists use ALMA to explain aluminum oxide enrichment around AGB stars
Narrow dense rings of comets are coming together to form planets on the outskirts of at least three distant solar systems, astronomers have found in data from a pair of NASA telescopes.
Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. In a new study, the researchers have traced back the dichotomy in the angular momentum of spiral and elliptical galaxies to their different formation history. In particular, the low angular momentum of ellipticals is mainly originated by nature in the central regions during the early galaxy formation process.
An international team of astronomers, led by Dutch scientists, has discovered a region in our Milky Way that contains many nitrogen compounds in the southeast of a butterfly-shaped star formation disk and very little in the north-west.
Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Perhaps part of the allure is that these enigmatic objects have never actually been “seen”. But this could now be about to change as an international team of astronomers is connecting a number of telescopes on Earth in the hope of making the first ever image of a black hole.
It might sound trite to say that the Universe is full of mysteries. But it’s true.
Astronomers have used NASA’s Chandra X-ray Observatory and other telescopes to show that a recently-discovered galaxy is undergoing an extraordinary boom of stellar construction.
Astronomers have found a distinct structure involving spiral arms in the reservoir of gas and dust disk surrounding the young star Elias 2-27.
