NASA’s exoplanet-hunting mission catches a natural comet outburst in unprecedented detail

NASA’s exoplanet-hunting mission catches a natural comet outburst in unprecedented detail Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers at the University of Maryland (UMD), in College Park, Maryland, have captured a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach of comet 46P/Wirtanen in […]

Gas giant composition not determined by host star

Gas giant composition not determined by host star A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn’t a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according to new work led by Carnegie’s Johanna Teske and published in the […]

Heavyweight in the heart of the Abell 85 central galaxy

Heavyweight in the heart of the Abell 85 central galaxy In space, black holes appear in different sizes and masses. The record is now held by a specimen in the Abell 85 cluster of galaxies, where an ultra-massive black hole with 40 billion times the mass of our sun sits in the middle of the […]

Gamma-ray binary HESS J0632+057 contains a pulsar, study suggests

Gamma-ray binary HESS J0632+057 contains a pulsar, study suggests Using NuSTAR spacecraft and the VERITAS array of telescopes, an international team of astronomers has investigated a gamma-ray binary known as HESS J0632+057. The study found that a compact object in this system is most likely a pulsar—a highly magnetized, rotating neutron star emitting beams of […]

Astronomers propose a novel method of finding atmospheres on rocky worlds

Astronomers propose a novel method of finding atmospheres on rocky worlds When NASA’s James Webb Space Telescope launches in 2021, one of its most anticipated contributions to astronomy will be the study of exoplanets—planets orbiting distant stars. Among the most pressing questions in exoplanet science is: Can a small, rocky exoplanet orbiting close to a […]

Ultraluminous X-ray source UGC 6456 ULX investigated in detail

Ultraluminous X-ray source UGC 6456 ULX investigated in detail Russian astronomers have performed a detailed study of one of the ultraluminous X-ray sources (ULXs) in the galaxy UGC 6456. Results of the research, presented in a paper published November 20 on arXiv.org, suggest that this source, designated UGC 6456 ULX, is one of the brightest […]
