NuSTAR images of XTE J1858+034 as observed in November 2019. Credit: Malacaria et al., 2021. Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), an international team of astronomers has conducted X-ray observations of an accreting X-ray pulsar known as XTE J1858+034. Results of the study, presented in a paper published January […]

The TRAPPIST-1 system has long be studied by exoplanet hunters due to its unique quantity of planets that happen to also be Earth sized. In a recent paper, a team of scientists led by Erik Agol at the University of Washington, dove into more detail on the density of the seven known planets in […]

ANIMATION Using a combination of telescopes, including the Very Large Telescope of the European Southern Observatory (ESO’s VLT), astronomers have revealed a system consisting of six exoplanets, five of which are locked in a rare rhythm around their central star. The researchers believe the system could provide important clues about how planets, […]

On the left is an image of the Jewel Bug Nebula (NGC 7027) captured by the Hubble Space Telescope in 2019 and released in 2020. Further analysis by researchers produced the RGB image on the right, which shows extinction due to dust, as inferred from the relative strength of two […]

ANIMATION Albert Einstein’s theory of general relativity profoundly changed our thinking about fundamental concepts in physics, such as space and time. But it also left us with some deep mysteries. One was black holes, which were only unequivocally detected over the past few years. Another was “wormholes” – bridges connecting different points […]

An image of the nearby Pleiades star cluster. CfA astronomer Guillermo Torres has completed a detailed eleven-year study of intermediate mass stars in this cluster using SAO’s Fred L. Whipple Observatory Tillinghast facility. Because these stars are rapidly rotating, previous spectroscopic measurements of their motions and properties had been unreliable. […]
