Equinox

March 20, 2017

Equinox

March 20, 2017 marks the Equinox, when day and night are of equal length. The March Equinox is often called the Spring or Vernal Equinox in the Northern Hemisphere (where days will now get longer) and the Fall or Autumn Equinox in Southern latitudes (where days will start to shorten).

Okay, days still stay 24 hours long, it’s the periods of daylight that get longer and shorter. Come on, lighten up. The UN says March 20th is also the International Day of Happiness.

Space Aliens Communicate With Earth. Maybe.

January 3, 2017

Space Aliens Communicate With Earth. Maybe.

“Two Canadian astronomers published a study that claims an anomaly in the pulsing of a group of stars is possibly evidence of an alien civilization. ….

The scientists Ermanno Borra and Éric Trottier from the Université Laval in Quebec analyzed modulations in 2.5 million stars from the Sloan Digital Sky Survey project and concluded that 234 of them exhibited strange behavior. In fact, the stars seemed to be signaling, with the conceivable explanation that it’s aliens trying to make contact.”

— “Astronomers Detect Strange Star Signals That Are ‘Probably’ Aliens Making Contact,” Paul Ratner, Big Think

“Either stars are strange, or there are 234 aliens trying to contact us,” Evan Gough, Universe Today via Phys.org

Comet Lander: It’s Alive!

June 15, 2015

Comet Lander: It's Alive!

The Philae device the European Space Agency landed on a comet has emerged from 7 months of hibernation and phoned home, sending a radio signal from Comet 67P. The ESA Rosetta Orbiter landed Philae after a 10 year space voyage, but the washing-machine-sized device bounced into a shadowed part of the comet’s surface and couldn’t recharge its solar cells until now.

“European space probe, thought lost, awakes in comet’s shadows,” Thomas Atkins, Reuters

European Space Probe Lands on a Comet

November 12, 2014

European Space Probe Lands on a Comet

7 hours after Europe’s Rosetta orbiter launched Philae, a washing-machine-sized robot probe, it landed on Comet 67P/Churyumov-Gerasimenko, a big ball of ice and rock 314 million miles away and traveling through space at 34,000 miles an hour. The ESA probe will remain there transmitting data until August 2015 as the comet slowly melts from the heat of the sun.

The international space mission has been a long time in the making. Comet-chasing Rosetta was launched ten years ago. The scientific importance of the Rosetta mission cannot be over-estimated. Comets are frozen repositories of early stages of the solar system.

India Goes to Mars!

India’s Mars Orbital Mission (MOM), also known as Mangalyaan, has left Earth orbit en route to the Red Planet. The unmanned probe, launched from Sriharikota in Andhra Pradesh on November 5th and is scheduled to reach and orbit Mars in September, according to the Indian Space Research Organisation (ISRO). India’s project cost $80.3 million, less than a sixth of NASA’s $455 million Mars probe. You can follow India’s Mars mission on Twitter: @Mangalyaan1
