Astronomers using the Hubble Space Telescope have discovered that the blowtorch-like jet blasting from a supermassive black hole at the core of galaxy M87 seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but are apparently in a dangerous neighborhood nearby. Hubble found twice as many novae going off near the jet as elsewhere in the giant galaxy during the surveyed time period.

Scientists at BFU named after Kant Immanuel, doctor of Physics and Mathematics Artyom V. Astashenok and Alexander S. Tepliakov have proved the viability of a holographic dark energy model. Such model was considered unstable and therefore wasn’t widely used for describing the acceleration in the expansion of the Universe. The results of the research have been published in the Physics Letters B magazine.

Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to earth-bound samples from the same source.

Observations using the Dark Energy Camera (DECam) confirm astronomers’ expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam’s exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results.

Observaciones realizadas con la Cámara de Energía Oscura (DECam, por sus siglas en inglés) confirman las expectativas de los astrónomos de que los cuásares del Universo primitivo se formaron en regiones del espacio densamente pobladas con galaxias compañeras. El enorme campo de visión de DECam y sus filtros especiales jugaron un papel fundamental para llegar a esta conclusión. Además, estas observaciones revelan la razón por la que los estudios previos que buscaban caracterizar la densidad de los vecindarios de los cuásares en el Universo primitivo arrojaban resultados contradictorios.

Arp 107, a pair of interacting galaxies, shines brightly in high-resolution infrared light. A collision, which occurred hundreds of millions ago, created a tenuous bridge of gas and dust that connects the two galaxies, and started a new wave of star formation that NASA’s James Webb Space Telescope captures clearly.

Using Hubble, astronomers have found more black holes in the early universe than previously thought. They went black hole hunting in the landmark Hubble Ultra Deep Field, first revealed in 2004, and in following observations to look for supermassive black holes.
