Tag: “Milky Way”

An impression of the encounter between the Milky Way galaxy and the smaller "Sausage" galaxy about 8 billion to 10 billion years ago. The record of this ancient encounter is still preserved in the velocities and chemistry of the stars. (V. Belokurov (Cambridge, UK); Based on image by ESO/Juan Carlos Muñoz)

Astronomers Discover Ancient Galactic Collision that Reshaped the Milky Way

July 6, 2018

A team of astronomers found evidence of a cataclysmic collision between the Milky Way and a dwarf galaxy some 8 to 10 billion years ago. The astronomers refer to this galactic crash as a ‘defining event’ in the early history of the Milky Way. They say the collision between our galaxy, and what is being […]

Recent Green Bank Telescope and Australia Telescope Compact Array observations have identified the telltale radio signal of diamond dust around 3 such stars, suggesting they are a source of the so-called anomalous microwave emission.

Astronomers Detect Nanodiamonds in Three Baby Star Systems

June 11, 2018

Astronomers have detected swirls of diamonds, hundreds of thousands of times smaller than a grain of sand, in the protoplanetary or circumstellar disks of three baby star systems in the Milky Way – V892 Tau, HD 97048, and MWC 297. After conducting a series of observations with the US National Science Foundation’s Green Bank Telescope […]

Breakthrough Listen’s Search For ETI Gets Boost

May 15, 2018

The Breakthrough Listen initiative’s search for extra-terrestrial intelligent life just got a big boost thanks to hardware upgrades at Australia’s Parkes Radio Telescope. The upgraded equipment will help scientists conduct faster surveys of the sky and will provide an ability to scan the Milky Way’s disk and bulge in unparalleled detail. The Australian radio telescope […]

Galaxy Megamergers 1.4 – 1.5 Billion Years after the Big Bang

April 26, 2018

Two teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder Experiment (APEX), in Chile, to observe dense concentrations of so-called “starburst” galaxies. With these galaxies packing together so closely, the scientific teams realized that they were getting ready to violently collide and merge with each other, which would eventually […]

Astronomers Search for the Sun’s Long-Lost Solar Siblings

April 20, 2018

While a family reunion is highly unlikely, Australian and European astronomers are still trying to find our Sun’s long-lost solar siblings which are now scattered throughout the sky. To do so, the scientists examined the of some 350,000 stars in the Milky Way – as though they were mapping each star’s DNA. The sun was […]

This is a galaxy that's been catalogued as NGC 1052-DF2. Astronomers call it the "see-through" galaxy since you can see right through it and observe other and more distant galaxies behind it. Researchers have found that the galaxy is missing most, if not all, of its dark matter. (NASA, ESA, and P. van Dokkum (Yale University))

A Galaxy is Missing Its Dark Matter

April 2, 2018

Scientists say that the invisible and mysterious dark matter makes up about 27% of all material in the universe. Regular or normal matter that you see and touch every day takes up 5% and the remaining 68% comes from an enigmatic form of energy called dark energy. According to NASA, dark matter serves as a type of […]

First Interstellar Visitor Probably Came From Binary Star System

March 21, 2018

Canadian astronomers think that the first confirmed interstellar object to enter our solar system, a rocky, cigar-shaped asteroid called ‘Oumuamua, probably came from a binary star system. To make their findings, the researchers at the University of Toronto’s Center for Planetary Science checked into just how effective twin star systems are at ejecting objects like […]

Milky Way and Andromeda Galaxies Have the Same Mass

February 16, 2018

In 2012, NASA astronomers predicted that our Milky Way galaxy will collide and merge with its neighboring Andromeda galaxy in about 4 billion years. Scientists said that when this galactic collision takes place, Andromeda, which was thought to be two to three times the size of the Milky Way – will completely engulf our galaxy. Now, […]

First Extragalactic Planets Found

February 6, 2018

No doubt you’ve heard about extrasolar or exoplanets; planets that were discovered orbiting a star outside of our own solar system. Nearly 3,000 of these planets have been confirmed so far, with many more candidate planets waiting to be verified. However, these planets have all been discovered within our own Milky Way galaxy. An astrophysics […]

JPL Fires Up Voyager 1 Thrusters after 37 Year Rest Imagine you’ve discovered a rare gem of a car that’s been tucked away in a barn for the last 37 years. The barn’s owner says it’s yours if you can drive it away. But if you’ve ever tried to start a motor vehicle and keep it […]
