Sun sneezes and…

POSTED BY: DIMITRA ATRI
 
Living near a star has its benefits but one has to face consequences too. Last week we witnessed a M9 class solar flare and an intense Coronal Mass Ejection (CME) hitting the Earth. CMEs are large volumes of charged particles ejected from the Sun’s Corona. Interaction of these charged particles with the atmosphere gives rise to spectacular auroras which can now be found floating around on youtube. Solar Storm in the Earth’s atmosphere The strongest such event in recorded history....

Countdown to 12/20/11

POSTED BY: DIMITRA ATRI
 
Here is today’s countdown coming from what is called the Queen of the Himalayas (Mount Everest pictures later!). 4. Earth-size exoplanets With better senstivity of telescopes, it is now possible to observe Earth-size exoplanets! However, we need bigger telescopes to observe their atmospheric spectra and figure out whether there are any signs of life. http://www.bbc.co.uk/news/science-environment-16268950 3. Dust avalanches on Mars Mars has a very thin atmosphere, and anything falling from space directly impacts its surface without much hindrance. Recently, it....

Super Earths, Higgs and Black holes

POSTED BY: DIMITRA ATRI
 
3. What’s with Super Earths? The ever increasing number of exoplanets is putting the models of planet formation to test. A new class of planets, named “super-Earths” have emerged. These planets, about a third of the observed ones, have sizes between the Earth and Neptune. Here is the story. 2. Higgs? I spent the whole of Tuesday, attending talks and discussing physics with colleagues here and at CERN. It was a special occasion since we had a great discussion on....

Exoplanets, supermassive blackholes and Higgs…Countdown to 12/6/11

POSTED BY: DIMITRA ATRI
 
4. Exoplanet detected in the habitable zone! Kepler mission recently found an exoplanet, Kepler-22b right in the middle of the habitable zone of a Sun-like star. For some reason, I am unable to access the Kepler mission’s website at this moment, but here is a description. I must mention that at present there is not enough information to call it an Earth-like planet, contrary to what several media outlets are reporting. Video of the press release can be found here.....
