NASA’s former chief exploration scientist, Michael Wargo, has been posthumously honored with the distinction of having a lunar crater named after him. Wargo Crater is…
Roughly 50 million light-years away lies a somewhat overlooked little galaxy named NGC 1559. Pictured here by Hubble’s Wide Field Camera 3, this barred spiral…
A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing–an astronomical phenomenon…
A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that…
The South Pole Telescope (SPT) is a 10-meter-diameter telescope in the Antarctic that has been operating at millimeter- and submillimeter-waves for a decade; the CfA…
A dark cloud of cosmic dust snakes across this spectacular wide field image, illuminated by the brilliant light of new stars. This dense cloud is…
Astrophysicists from Heidelberg, Garching, and the USA present the thus far largest and most detailed calculations of the formation and evolution of galaxies. In their…
A new self-portrait of NASA’s Curiosity Mars rover shows the vehicle on Vera Rubin Ridge, which it has been investigating for the past several months….
Data from NASA’s Spitzer and Hubble space telescopes have been combined to show this image of distant interacting galaxies in light that spans the visible…
This project, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, has made a map with 300 galaxies close to the Milky Way,…
An international team of astronomers led by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias (IAC), finds signs that the outer halo of…
An International team with participation by researchers with close links to the Instituto de Astrofísica de Canarias and the University of La Laguna, obtains the…
The year 1958 held much promise for the United States space program. Both the US and the Soviet Union were preparing to orbit a satellite…
The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place. Unlike the Milky Way, this semi-spiral collection of a…
For the first time, scientists have estimated how much energy is transferred from large to small scales within the magnetosheath, the boundary region between the…
The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were…
This new image from NASA’s Mars Reconnaissance Orbiter (MRO) shows layers, probably sedimentary in origin, that have undergone extensive erosion in Shalbatana Valles, a prominent…
