Science Magazine: Zoom on the galactic centre

Astronomers have found a dozen very old variable stars deep in the maelstrom of stars at the center of our Milky Way galaxy. The discovery may help researchers decide which of two theories best explains how a “galactic bulge”—the pileups of stars at the galaxy’s center—forms.  

Caltech: The Making of the Milky Way

Simulated view of the formation of our Milky Way galaxy. The simulation begins moments after the birth of the universe 13.8 billion years ago and ends with our mature, present-day Milky Way galaxy. Pockets of matter are seen growing in size, and merging with each other, due to the force of gravity. The clock in …

Harvard University: John Asher Johnson, “Hot on the Trail of Warm Planets Around Cool Stars”

Just three years ago the prospect of finding temperate, rocky worlds around other stars was still the subject of science fiction: none had been found and reasonable estimates put us years or decades away from such a momentous discovery. All of that has changed very recently on the heels of the extraordinarily successful NASA Kepler …

NASA: Hubble Directly Images Possible Plumes on Europa

NASA’s Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images. This adds another piece of supporting evidence to the existence of water vapor plumes on Europa – Hubble also …

VOX: The 1995 Hubble photo that changed astronomy

The Hubble Deep Field, explained by the man who made it happen. One of the main scientific justifications for building Hubble was to measure the size and age of the Universe and test theories about its origin. Images of faint galaxies give ‘fossil’ clues as to how the Universe looked in the remote past and …

ESA: First data from ESA’s Gaia mission

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of roughly 1% of the total population of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy. The first …

NASA Goddard: Young Cryovolcano on Ceres

Analysis of images from NASA’s Dawn mission reveals that dwarf planet Ceres hosts an unexpectedly young cryovolcano that formed with the past billion years. Click this link Ice volcano spotted on Ceres for more information.  

NASA Goddard: Snapshots from the Edge of the Sun

For the first time, using NASA’s Solar Terrestrial Relations Observatory, or STEREO, scientists have imaged the edge of the sun and described that transition – from which the solar wind blows. Defining the details of this boundary helps us learn more about our solar neighborhood, which is bathed throughout by solar material – a space …

Harvard University: Sarah Stewart, “The Violent Origin of the Earth and Moon”

The physical properties of our planet are intricately tied to the sequence of giant impact events that led to the formation of the Moon. The canonical giant impact model for lunar origin has been called into question by recent geochemical measurements of lunar rocks. Professor Stuart presents a new model for the origin of the …

Slooh: Earth’s Newest Neighbor

Join Slooh to explore Proxima-b a brand new, Earth-like planet, within driving distance of our own planet. During the broadcast host Eric Edelman was joined by Michael Endl from the McDonald Observatory at the University of Texas at Austin, who worked on the ESO team that made the discovery. They’ll discuss how the team managed …

Nature video: The exoplanet next door

Astronomers have discovered evidence of a small, rocky planet orbiting our nearest star – and it may even be a bit like Earth. Nobody knows whether the planet, called Proxima b, could ever sustain life. The little planet orbits our sun’s nearest neighbouring star, Proxima Centauri, making it the closest exoplanet ever found. More on …

European Southern Observatory: Artist’s impression of planet orbiting in the HD 131399 system

Published on Jul 7, 2016 This artists impression shows the orbit of the planet in the triple-star system HD 131399. Two of the stars are close together and the third, brighter component is orbited by a gas giant planet named HD 131399Ab. Located about 320 light-years from Earth in the constellation of Centaurus (The Centaur), …
