Curious facts about cosmic life and their inhabitants.

Saturn is a lovely planet, with its magnificent system of gossamer rings, shining moons of ice, and myriads of glimmering, frozen, dancing moonlets that twirl and somersault both inside and outside of the enchanting system of rings.



and here is another

The astronomers found that larger craters, which excavated pits much deeper into the Moon's surface, only increased porosity in the underlying crust. This indicates that these deeper layers have not reached a steady state in porosity, and are not as fractured as the megaregolith.



and finally

"Impact simulations indicate that impacts into a hot, thin crust representative of the early Moon's near-side hemisphere would have produced basins with as much as twice the diameter as similar impacts into cooler crust, which is indicative of early conditions on the Moon's far-side hemisphere," noted lead study author Dr. Katarina Milijkovic in the November 7, 2013 JPL Press Release. Dr. Milijkovic is of the Institut de Physique du Globe de Paris.

Full Moon Day is celebrated on June 18th. If you are a lover and miss your beloved's company when the whole world in basking in the soft, sensuous glow of moonlight, this is the perfect time to reach out with your warm, romantic messages. You could do it with online cards. Just make sure that a wonderful night of opportunities doesn't slip by, unattended and untapped.



The team of astronomers used the same HST technique to observe the little moon as they did for discovering the small moons of Pluto in 2006, 2011, and 2012. Several earlier hunts around Makemake had not succeeded in spotting it. "Our preliminary estimates show that the moon's orbit seems to be edge on, and that means that often when you look at the system you are going to miss the moon because it gets lost in the bright glare of Makemake," commented Dr. Alex Parker in an April 28, 2016 Hubble Press Release. Dr. Parker, who led the image analysis for the observations, is of the Southwest Research Institute in Boulder, Colorado.



Now speaking of size within the Solar System, well, let us just say that the Sun is unmatched. Did you know that the Sun comprises more than 99% of the total mass of the entire solar system? Jupiter actually takes up much of the remaining proportion. Surface temperatures on the Sun stand at 5000 Kelvins (4727 degrees Celsius). With temperatures at its core reaching a 15.6 million Kelvins (15.6 million Celsius), the Sun is truly a celestial spectacle. It gets even better when one realizes that the Sun is classified as a class G star. Stars are classified in six major categories that tie in to the surface temperature and brightness. The categories are M, K, G, F, A, B and O listed in ascending order brightness and surface temperature. You can see that the Sun falls on the lower end of this classification. Category B and O are rare in the universe while most stars are in the category M and emit less heat and light energy. That said, the Sun is within the 90th percentile by mass among all stars. We have found other stars that are larger than our sun: one is estimated to be approximately 60,000 times bigger.
