Astronomers Find and Confirm 44 New Extrasolar Planets

August 10, 2018

An international team of astronomers has confirmed the existence of 44 new extrasolar planets. The planets were first spotted by the astronomers through data gathered from Campaign #10 of NASA’s Kepler K2 mission. According to NASA’s Kepler and K2 webpage, campaign #10 ran from July 6, 2016, to September 20, 2016. To verify their findings, […]

Mars In The News

July 27, 2018

Two new studies about Mars made news this week. Liquid Water Lake Detected on Mars First, a group of Italian scientists announced that they detected a 20-kilometer-wide lake of liquid water located about 1.5 kilometers beneath the ice of the southern polar ice cap of Mars. The scientists analyzed more than three years of data […]

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 […]

Calculations Show Mercury Has a Thin but Dense Crust

May 1, 2018

Mercury is the closest planet to the Sun, and very little is really known about this hot rocky orb. So far, only two space probes have ever studied Mercury. NASA’s Mariner 10 flew past the planet three times between 1973 and 1974. The flybys allowed scientists to map about half the planet, discover its thin […]

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 […]

ESA Mars Orbiter Gets A Software Upgrade

April 13, 2018

If you own any kind of computing device, whether it’s a smartphone, tablet, laptop or desktop computer, you know sooner or later that you’re going to have to update or install new software to keep it functioning. The same thing can also be said about spacecraft that have been in service for a while. The […]

Chinese Space Station Expected To Fall to Earth Within Days

March 28, 2018

Aerospace experts say they expect the Chinese space station, Tiangong-1, or “Celestial Palace 1” in English, to drop out of orbit and fall to Earth sometime between March 30th and April 2nd. Considering its orbital path and expected reentry trajectory, the experts say the space station could fall anywhere in the world between nearly 43° north […]

This is a NASA/ESA Hubble Space Telescope image of Galaxy NGC 6753 was released on September 18th. This galaxy is said to be one of only two known spiral galaxies that were both massive enough and close enough to permit detailed observations of their galactic coronas, which can only be detected by their X-ray emissions.
