Advice for stirring your online community and fostering engagement

When you enter into any new area of science, you almost always find

yourself with a baffling new language of technical terms to learn before you can converse with the experts. This is certainly true in astronomy both in terms of terms that refer to the cosmos and terms that describe the tools of the trade, the most prevalent being the telescope. So to get us off of first base, let’s define some of the key terms that pertain to telescopes to help you be able to talk to them more intelligently. The first area of specialization in telescopes has to do with the types of telescopes people use. The three designs of telescopes that most people use are the Refractor, the Reflector and the Schmidt Cassegrain telescope. The refractor telescope uses a convex lens to focus the light on the eyepiece. The reflector telescope has a concave lens which means it bends in. It uses mirrors to focus the image that you eventually see. The Schmidt Cassegrain telescope uses an involved system of mirrors to capture the image you want to see. A binocular telescope uses a set of telescopes mounted and synchronized so your view of the sky is 3-D. Beyond the basic types, other terms refer to parts of the telescope or to the science behind how telescopes work. Collimation is a term for how well tuned the telescope is to give you a good clear image of what you are looking at. You want your telescope to have good collimation so you are not getting a false image of the celestial body. Aperture is a fancy word for how big the lens of your telescope is. But it’s an important word because the aperture of the lens is the key to how powerful your telescope is. Magnification has nothing to do with it, its all in the aperture.

Hi would you mind stating which blog platform you're working with?
I'm planning to start my own blog in the near future but I'm having a hard time making a decision between BlogEngine/Wordpress/B2evolution and Drupal.
The reason I ask is because your layout seems different then most blogs and I'm looking for something completely unique.
P.S Apologies for getting off-topic but I had to ask!

Europe’s secret season for travel starts now
kraken darknet

Summer might be the most popular season for tourism to Europe, but it hardly promises a calm, cool and collected experience.

Who can forget this summer’s protests against overtourism in Barcelona and Mallorca, the wildfires that raged across Greece during the country’s hottest June and July on record and selfie stoplights to help control crowds on the clogged streets of Rome and Florence?

For travelers looking to avoid all that — as well as break less of a sweat literally and financially — welcome to Europe’s secret season.

From roughly mid-October to mid-December, shoulder season for travel to Europe comes with fewer crowds, far more comfortable temperatures in places that skew scorching hot during the summer months and plunging prices on airfare and accommodation.

Plunging prices
“The cheapest time to fly to Europe is typically from about the middle point of October to the middle point of December,” said Hayley Berg, lead economist at travel platform Hopper. “Airfare prices during those eight or nine weeks or so will typically be about an average of 40% lower than prices in the peak of summer in June.”

Hopper’s data shows that airfare to Europe from the United States during the period between October 20 and December 8 is averaging between $560 and $630 per ticket — down 9% from this time last year and 5% compared to the same timeframe in 2019.
