Astronomy: October 2019



Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego's Alison Coil, Rhodes College's David Rupke and a group of collaborators from around the world made a novel discovery.


A carved-out cloud of gas and dust looks like a celestial jack-o'-lantern in this image from NASA's Spitzer Space Telescope.


This Hubble Picture of the Week shows the spiral galaxy Messier 98, which is located about 45 million light-years away in the constellation of Coma Berenices (Berenice's Hair).


In celebration of Halloween, this new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face.


Astronomers using data from NASA's Chandra X-ray Observatory and other telescopes have put together a detailed map of a rare collision between four galaxy clusters.


For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars.


New measurements of the rate of expansion of the universe, led by astronomers at the University of California, Davis, add to a growing mystery: Estimates of a fundamental constant made with different methods keep giving different results.


A team of astronomers including assistant professor Kate Whitaker at the University of Massachusetts Amherst reports today that they have by chance discovered faint traces of a huge galaxy never seen before, dating from the early universe.


Grab a mixing bowl from your kitchen, throw in a handful of aluminum balls, apply some high voltage, and watch an elegant dance unfold where particles re-arrange themselves into a distinct "crystal" pattern.


On a typical day at the world's biggest laser, the National Ignition Facility (NIF) in Livermore, California, you can find scientists casually making star-like conditions using 192 high-powered lasers.


"Weather" in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge.


The birthplaces of planets are disks made out of gas and dust.


At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas.


Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation.


The center of our Milky Way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas.


Our Milky Way is a frugal galaxy. Supernovas and violent stellar winds blow gas out of the galactic disk, but that gas falls back onto the galaxy to form new generations of stars.


Physicists at Stockholm University and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionise the search for the elusive dark matter.


The two baby stars were found in the [BHB2007] 11 system - the youngest member of a small stellar cluster in the Barnard 59 dark nebula, which is part of the clouds of interstellar dust called the Pipe nebula.


The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy.


Astronomers have uncovered two historic events in which the Andromeda Galaxy underwent major changes to its structure.


An international team of astronomers with participation by researchers from DAWN, Niels Bohr Institute, University of Copenhagen has discovered a protocluster of galaxies 13.0 billion light years away using the Subaru, Keck, and Gemini Telescopes in Hawaii.


A new infrared image from NASA's Spitzer Space Telescope shows a cloud of gas and dust full of bubbles, which are inflated by wind and radiation from young, massive stars.


Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University.
