Projectile cannon experiments show how asteroids can deliver water

Science Daily Astronomy - Wed, 2018-04-25 16:20
New research shows that a surprising amount of water survives simulated asteroid impacts, a finding that may help explain how asteroids deposit water throughout the solar system.

Assembly of massive galaxy cluster witnessed for the first time

Science Daily Astronomy - Wed, 2018-04-25 13:18
For the first time, astronomers have witnessed the birth of a colossal cluster of galaxies. Their observations reveal at least 14 galaxies packed into an area only four times the diameter of the Milky Way's galactic disk. Computer simulations of the galaxies predict that over time the cluster will assemble into one of the most massive structures in the modern universe.

Molecular evolution: How the building blocks of life may form in space

Science Daily Astronomy - Wed, 2018-04-25 12:02
In an experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia and carbon dioxide, the building blocks of life. The experiment tested how the combination of electrons and basic matter leads to more complex biomolecule forms -- and perhaps eventually to life forms.

Milky Way's supermassive black hole may have 'unseen' siblings

Astronomers predict that galaxies with a mass similar to the Milky Way should host several supermassive black holes.

Uncovering the secret law of the evolution of galaxy clusters

Science Daily Astronomy - Tue, 2018-04-24 09:37
Using observational data from the Hubble Space Telescope and the Subaru Telescope, the size and mass of galaxy clusters have precisely been measured. The research team analyzed those data and found a simple law that regulates the growth of the clusters. They also showed that the clusters are still young and growing. The newfound law will serve as a tool to clarify the evolutionary history of clusters and the universe.

Face recognition for galaxies: Artificial intelligence brings new tools to astronomy

Science Daily Astronomy - Mon, 2018-04-23 12:51
A machine learning method called 'deep learning,' which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. In a new study, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.

Vast stellar nursery of Lagoon Nebula

Science Daily Astronomy - Thu, 2018-04-19 13:09
This colorful cloud of glowing interstellar gas is just a tiny part of the Lagoon Nebula, a vast stellar nursery. This nebula is a region full of intense activity, with fierce winds from hot stars, swirling chimneys of gas, and energetic star formation all embedded within a hazy labyrinth of gas and dust.

NASA planet hunter on its way to orbit

Science Daily Astronomy - Thu, 2018-04-19 10:57
NASA's Transiting Exoplanet Survey Satellite (TESS) launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life. Researchers will use spectroscopy to determine a planet's mass, density and atmospheric composition. Water, and other key molecules, in its atmosphere can give us hints about a planets' capacity to harbor life.

Optimizing space travel efficiency

Sending a human into space and doing it efficiently presents a galaxy of challenges. Scientists have explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, to create a framework to optimize fuel and other resources.

Meteorite diamonds tell of a lost planet

Science Daily Astronomy - Wed, 2018-04-18 14:48
Scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury to Mars.
