    The surprising discovery of a new class of pulsating X-ray stars
    https://phys.org/news/2017-03-discovery-class-pulsating-x-ray-stars.html

    A surprising new class of X-ray pulsating variable stars has been discovered by a team of American and Canadian astronomers
    led by Villanova University's Scott Engle and Edward Guinan. Part of the Villanova Secret Lives of Cepheids program, the new
    X-ray observations, obtained by NASA's Chandra X-ray Observatory and published Thursday, March 23rd in the Astrophysical Journal,
    reveal that the bright prototype of Classical Cepheids, d Cephei, is a periodic pulsed X-ray source.

    This view looks toward the sunlit side of the rings from about 38 degrees above the ring plane.
    The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 9, 2017.

    The view was obtained at a distance of approximately 70,000 miles (113,000 kilometers) from Saturn and
    at a Sun-Saturn-spacecraft, or phase, angle of 11 degrees. Image scale is 2,300 feet (690 meters) per pixel.

    HubbleSite: News - Gravitational Wave Kicks Monster Black Hole Out Of Galactic Core
    http://hubblesite.org/news_release/news/2017-12

    Runaway black hole is the most massive ever detected far from its central home

    Normally, hefty black holes anchor the centers of galaxies. So researchers were surprised to discover a supermassive black hole
    speeding through the galactic suburbs. Black holes cannot be observed directly, but they are the energy source at the heart of
    quasars — intense, compact gushers of radiation that can outshine an entire galaxy. NASA's Hubble Space Telescope made
    the discovery by finding a bright quasar located far from the center of the host galaxy.

    Researchers estimate that it took the equivalent energy of 100 million supernovas exploding simultaneously to jettison the black
    hole. What could pry this giant monster from its central home? The most plausible explanation for this propulsive energy is that
    the monster object was given a kick by gravitational waves unleashed by the merger of two black holes as a result of a collision
    between two galaxies. First predicted by Albert Einstein, gravitational waves are ripples in the fabric of space that are created
    when two massive objects collide.

    Astronomers find unexpected, dust-obscured star formation in distant galaxy
    https://phys.org/news/2017-03-astronomers-unexpected-dust-obscured-star-formation.html

    Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing,
    University of Massachusetts Amherst astronomer Alexandra Pope and colleagues report that they have detected a surprising rate of
    star formation, four times higher than previously detected, in a dust-obscured galaxy behind a Frontier Fields cluster.

    As Pope explains, "This very distant, relatively typical galaxy is known to us, and we knew it was forming stars, but we had no idea
    what its real star-formation rate was because there is so much dust surrounding it. Previous observations couldn't reach past that.
    Finding out that 75 percent of its star formation was obscured by dust is remarkable and intriguing. These observations clearly show
    that we have more to learn."

    She adds, "Historians want to know how civilizations were built up, and we astronomers want to know where and how the elements in the
    universe were formed and where everything is made of, came from." The study is accepted for publication in The Astrophysical Journal.

    The new tool that has made such revelations possible is the 50-meter Large Millimeter Telescope (LMT) which has been observing as
    a 32-meter telescope located on an extinct volcano in central Mexico in "early science mode" since 2013. Operated jointly by UMass
    Amherst and Mexico's Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE), it offers astonishing new power to peer into
    dusty galaxies, the astrophysicist says.

    Astronomers study a rare multi-eclipsing quintet of stars
    https://phys.org/news/2017-03-astronomers-rare-multi-eclipsing-quintet-stars.html

    A team of astronomers led by Krzysztof Hełminiak of the Nicolaus Copernicus Astronomical Center in Toruń, Poland, has investigated
    an interesting bright quintuple stellar system in which each of the stars is eclipsed. The quintet, designated KIC 4150611 (also
    known as HD 181469), given its peculiar pulsations, eclipses, and high-order multiplicity, could provide important information on
    evolution and structure of multiple-star systems. The new research was published Mar. 2 in a paper on arXiv.org.

    KIC 4150611 is a quintuple star system that was initially identified as a visual binary star in 2001. However, the object's first
    position measurement dates back to 1831. The eclipses in the system were first noted in 2011 in the Kepler Eclipsing Binaries Catalog
    (KEBC). Shortly after, it was found that KIC 4150611 contains a hybrid delta Scuti (δ Sct)/gamma Doradus (γ Dor) pulsator. In 2015,
    a spectral analysis of this pulsator was performed and its atmospheric parameters were obtained, showing that it is a rapidly-rotating
    star of spectral type F1 V mA9.

    A very ordinary, isolated star varies by 20% in brightness on time scales from a day to a century. No one has yet proposed a convincing explanation.

    The star KIC 8462852 is reasonably advertised as the most mysterious star in our galaxy. It is by almost all measures a perfectly ordinary F2 main-sequence star,
    which is to say that it is middle-aged and stable. At a temperature of 6750 K, it’s a bit hotter than our sun, and at 1.43 solar masses, it’s a bit more massive too.
    Until 2015 the star was unnoticed in the wing of the constellation Cygnus (the Swan), though at a distance of about 1500 light-years and an optical magnitude of
    about 12, the star is visible with a small telescope. When it was noticed, it created quite a splash.
