  1. This artist’s illustration depicts the "tidal disruption event" (TDE) called ASASSN-14li, which is the focus of the latest study. As a star approached too closely to the supermassive black hole at the system, the strong gravity tore the star apart. This artist's impression depicts the aftermath of this destruction. After the star was ripped apart, some of its gas (red) was left orbiting around and falling into the black hole. A portion of the gas was driven away in a wind (blue).

  2. The sun is viewed from space and appears as a fiery red and orange sphere covering more than half of the image. A red and orange arc of plasma, which resembles fire, protrudes from the sun’s surface towards the bottom of the frame. The plasma extends from a very bright white section of the sun’s surface.

  4. Artist impression of a young planet-forming disk illustrating the respective locations of the soot and water-ice lines. Planets born interior to the soot line will be silicate-rich. Planets born interior to the water-ice line, but exterior to the soot line will be silicate and soot-rich (“Sooty Worlds”). Planets born exterior to the water-ice line will be water worlds.

  5. U-M graduate student Isaac Malsky, a co-author of the study, ran three-dimensional models for the planet, testing models with and without clouds and hazes, to see how these aerosols shape the thermal structure of the planet and help interpret the data.

  6. The rocky exoplanet GJ 486 b moves in front of its star, a red dwarf, the most common type of star in the universe. Astronomers detected a water vapor signal coming from either the planet or its star, using NASA's James Webb Space Telescope. Image credit: NASA, ESA, CSA, Joseph Olmsted (STScI)

    JWST sees water vapor near a distant planet—but is it in the planet’s atmosphere or its star?

  8. Yukun Sun, a graduate student research assistant, and William Leal, a research assistant, both in the Department of Naval Architecture and Marine Engineering at the University of Michigan, work together to set up an experiment where microplastic pellets are placed on the surface of the water in the wind wave tank at the Marine Hydrodynamics Laboratory to determine how they effect measurements of surface roughness on June 18, 2021.

  9. This NASA Hubble Space Telescope image shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689, containing about 1,000 galaxies and trillions of stars. Dark matter is an invisible form of matter that accounts for most of the universe's mass. Hubble cannot see the dark matter directly. Astronomers inferred its location by analyzing the effect of gravitational lensing, where light from galaxies behind Abell 1689 is distorted by intervening matter within the cluster. Researchers used the observed positions of 135 lensed images of 42 background galaxies to calculate the location and amount of dark matter in the cluster. They superimposed a map of these inferred dark matter concentrations, tinted blue, on an image of the cluster taken by Hubble's Advanced Camera for Surveys. If the cluster's gravity came only from the visible galaxies, the lensing distortions would be much weaker. The map reveals that the densest concentration of dark matter is in the cluster's core. Abell 1689 resides 2.2 billion light-years from Earth. The image was taken in June 2002. Image credit: NASA, ESA, D.

  15. A team led by University of Michigan postdoctoral researcher Evan Rich and professor John Monnier imaged 44 targets in a survey called Gemini-Large Imaging with GPI Herbig/T-tauri Survey, or Gemini-LIGHTS. The astronomers detected some form of dust around 80% of the 44 targets. The team released a gallery of 6 of the 44 targets showing a range of different morphologies that tell the researchers about the dynamics happening within the disk itself. Rich will present the summary paper's findings at the American Astronomical Society's annual meeting this month. His study has also been accepted for publication in the Astronomical Journal.
