In this month: September

26th September 1905 Einstein’s Theory of Special Relativity is published. It is the generally accepted and experimentally confirmed physical theory regarding the relationship between space and time and contains one of the most famous equations, e=mc2, which in simple terms means if you multiply a specific amount of mass by the speed of light squared you get its energy. 5th September 1977 Voyager 1 ( Image above courtesy NASA) is launched from Cape Canaveral to study the outer Solar System. Originally built to last five years it has operated for just on 42 years and still communicates with the Deep Space Network taking 19 hours to transmit data to Earth and will continue to do so until its po

Solar Observations: July 2019

For the month of July, 2019 and during my 21 days of solar observations I did not see any Sunspot activity. The only activity that was seen were Prominences. These were mostly faint and small. The most prominent was on the 8th reaching 47,000km in height, the 9th a Hedgerow Prominence on the NW limb reaching 65,000km high and 187,000km along the limb. On the 11th a Column type Prominence rose to 74,000km. On the 20th a Mound type Prominence reached 65,000km and on the 23rd a double Arched Prominence reached 47,000km high. Most other Prominences were small, faint and insignificant. No activity at all was seen on the Sun on the 7th 12th 13th 15th 16th 18th and 26th Also the Sun appeared to be

Did you know: time and space

This month ….. the incredibly quick to the incredibly long and everything in between It takes the Sun 225 million years to travel once around the centre of the Milky Way Galaxy. This is known as a galactic year or a cosmic year. A Pulsar is a neutron star that spins incredibly fast. The fastest known spinning pulsar, PSR J1748-2446ad, spins once every 1.4 milliseconds which is 716 times per second, or 42,960 times a minute.

It takes a photon of light only eight minutes to reach Earth from the Sun, but it can take 100,000 years for that photon to travel from the core of the Sun to the s
