The brightest galaxy in the Universe

© Afrim Constantin –

It’s called WISE J224607.57-052635.0 and a remote galaxy whose brightness record is equal to that produced by 300 trillion Suns. It was discovered by the NASA satellite, WISE and belongs to a new class of objects called ultra-luminous infrared galaxies. According to the authors of this study, published in the Astrophysical Journal, the super bright

Nasty 1: a star unique setting

© Afrim Constantin –

Thanks to the Hubble Space Telescope NASA a team of astronomers has discovered surprising new clues about a massive star rapidly aging. The star showed a behavior so strange, compared to others that we know in our galaxy, astronomers have nicknamed “Nasty 1” (literally “bad” or “sloppy”), a pun on the name of the catalog

Supernova in collision

© Afrim Constantin –

A team of astronomers from Caltech working on an automated observation system called intermediate Palomar Transient Factory has discovered a new type of Ia supernova that suggests the possibility of two distinct populations for this type of sources. The Type Ia supernovae are one of the brightest phenomena of the Universe, and are produced when

Rebuilt with an unprecedented level of detail, thanks to the array of radio telescopes in the Atacama, the structure and kinematics of an “OB association.” The study, published on ApJ, helps explain the mechanism of formation of clusters of massive stars. If the stars were people, this offers us today ALMA would be a kind

The symmetry between matter and antimatter

© Afrim Constantin –

A survey that has used the data collected by the LAT aboard the Fermi space telescope NASA suggests the presence of traces of helical magnetic fields in space, the ‘signature’ of the violation of the symmetry between matter and antimatter, which occurred in the first few moments after Big Bang. The universe is not large.

The new instrument Moonlight will be set up on the first four missions Moon Express to test the principles of the theory of general relativity enunciated by Albert Einstein, increasing our scientific knowledge of the moon, and also increasing the accuracy of the mapping of our satellite that will be used in future missions. Moonlight

Dragonfly Galaxies

The existence of the UDG, Ultra Diffuse Galaxies was confirmed. They are scattered clusters of stars that must accommodate proportionally much dark matter in order to be together. “If the Milky Way was a sea, then these galaxies would be the clouds,” says Pieter van Dokkum of Yale University. An international team of researchers, led

The retirement of white dwarfs

© Afrim Constantin –

Scientists have used Hubble to observe the white dwarfs in the cluster. These dying stars are migrating from the crowded center towards wider orbits outside. Astronomers knew this process but had never seen it in action. The Hubble Space Telescope of NASA / ESA, now 25-years-old, continues tirelessly to give us stunning images that shows
