  Wish List: Stargazing gadgets 2021. By: Barry Allen ||| April 1, 2021      Stellina  Bring the power of a stellar observatory to your back garden with Stellina by Vaonis. This next-generation telescope allows stargazers to select a planet, star or nebula, and Stellina will locate its position and begin imaging. As a highly sophisticated piece of technology, this compact telescope comes equipped with a rain sensor and will power down when weather conditions become harsh. This allows you to leave Stellina outside for long-exposure shots and mesmerising timelapse videos. Stellina also makes stargazing a social experience by removing eyepieces and sending observation images straight to your smartphone or computer for you to share on social platforms. Homestar Flux Bring the night sky indoors with the Homestar Flux by Sega Toys. This home planetarium can project more than 60,000 high-definition stars straight onto your ceiling. The Homestar Flux also lets you explo...

  Hurricane history: 8 destructive storms. By Barry Allen | March 31,2021 1. Okeechobee Date:  6-21 September 1928 Category:  5 Deaths:  4,000+ Okeechobee made landfall near West Palm Beach, Florida, late on 16 September, tearing up the land and homes and taking lives. Days before the hurricane had already claimed the lives of about 1,500 people in the Caribbean. The worst impacted area on the mainland was Lake Okeechobee, which gives the hurricane its name. This region was used primarily for farming, and although a small dyke had been built to protect the land, it was no match for Okeechobee’s 225-kilometre-per-hour winds. Many workers were drowned in the flooded fields, caused by a storm surge. 2. Labor Day Hurricane Date:  29 August – 10 September 1935 Category:  5 Deaths:  485 One reason why this hurricane cost the lives of hundreds is due to the underestimation of its scale. Hitting Florida Keys on 2 September, the hurricane obliterated the coast,...

  Biology/Physics-Origin of the different colors of things. By : Barry Allen | March 30,2021 To understand why various objects appear in different colours, we have to start with colour itself. What we perceive as colour is actually our brain’s interpretation of signals coming from the retina of our eyes. Such signals are triggered when electromagnetic waves fall onto the millions of light-sensitive cells covering the retina. The energy of an electromagnetic wave is associated with its frequency ( f , note that frequency times wavelength,  λ , gives the speed of light, which is constant  c  in vacuum). Visible lights only make up a tiny part of the whole spectrum of electromagnetic wave as shown below. Evolution results in that our eyes are only sensitive to those with frequency within the visible spectrum. Light from the sun contains electromagnetic waves of different wavelengths, mostly within the visible spectrum, when combined together, it appears white. One ...

  5 important space tragedies. By Barry Allen | March 31,2021 What did these events teach us about spaceflight? 1967: Apollo 1 fire NASA’s first manned Apollo spaceflight was set to be a practice launch to space for the first Moon landing, but while still on the ground the three astronauts inside were engulfed in a fatal fire. Flaws including flammable materials in the spacecraft and a difficult emergency escape were redesigned to create safer environments for future Apollo flights. 1967: Soyuz 1 experiment Sadly demonstrating the dangers of spaceflight under political pressure, a Soviet craft carried cosmonaut Vladimir Komarov to his death. 203 technical issues were reported before liftoff, but the flight went ahead anyway in an attempt to overtake the US in the Space Race. When Komarov’s parachute failed to open, he became the first person to die during a mission. 1986: Challenger's final flight The Challenger Space Shuttle had successfully become the second to fly to space, but ...
