Lyrid Meteor Showers Peak Apr 22nd

by vidur

Earth is passing through a debris field of meteors left behind by Comet Thatcher (C/1861 G1). These meteors manifest themselves to us as a Lyrids. Expected activity at peak is 10-20 meteors per hour. But since the weather is nice and warm outside AT NIGHT, its officially time to go out and enjoy these space rocks with friends and family.

Lyrids seem to radiate from the bright star Vega in Lyra ( hence the name Lyrids ). For those who are not that interesting in meteors should know that what they lack in activity they make up in brightness. Lyrid meteors are usually bright and chances of seeing fireballs are good.

Earth Like Planet Discovered

by vidur

Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting in the “habitable zone” of another star. The planet, named “Kepler-186f” orbits an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy. The discovery of Kepler-186f confirms the long held theory that planets the size of Earth exist in the habitable zone of stars other than our sun. This means that with similar climate profiles like earth, life similar to earth may exist elsewhere in the universe.

The “habitable zone” is defined as the range of distances from a star where liquid water might pool on the surface of an orbiting planet. While planets have previously been found in the habitable zone, the previous finds are all at least 40 percent larger in size than Earth and understanding their makeup is challenging.

Physicists Look for Evidence of time travellers on the internet

by vidur

Physicists R. Nemiroff (of APOD fame) and his student Teresa Wilson, recently published their results of a grand internet search to look for evidence of time travelers. In a nutshell they were looking for ‘time traveler activity’ over the internet, say a timer traveler used his time machine to move back in time and say…send an email, or put information online about world events that just happened way before it actually did. Time travel to the future is allowed by special relativity, however there is much debate if we can actually go back in time.

The search as you may have expected didn’t turn out much …. but made for a pretty good story.

Happy Equinox

by vidur

The Autumn equinox happens today Sept 22nd at 2044 UTC. This moment marks the official end of summer in the Northern hemisphere and hopefully New Delhi too! Hopefully the weather gods will get the memo too. The autumn equinox marks the time of equal length days and nights. From now on nights will become longer than days in the northern hemisphere. Hopefully that would mean that mortals can sleep a bit more.

Clear Skies

Saturn at its best Opposition

by vidur

Greetings Fellow Astronuts

Its a great time to go under the stars and look for Saturn. Today on April 28th the planet makes its closest pass to earth in all of 2013. Finding Saturn is easy. Just look south for a bright magnitude 0 star due west of Spica in Virgo.

Happy Hunting!
