Theme of this series, which is in an ongoing state, is the voyage from earth to exoplanet OGLE-2005-BLG-390Lb at a distance of approximately 21500 +- 3300 lightyears1 from earth. OGLE-2005-BLG-390Lb is a so called super earth exoplanet situated close to the center of our Milkey Way, Sagittarius A*. OGLE-2005-BLG-390Lb orbits it’s star OGLE-2005-BLG-390 approximately every 10 years (3500 earth days). It was first discovered in 2005 using the technique of gravitational micro lensing. Gravitational lensing in general is caused by lightbeams that are being bent by the gravitational fields of various astrophysical objects such as stars or even planets. As OGLE-2005-BLG-390Lb lies close to the center of the Milkey Way a journey to the exoplanet shows a lot of similarites to the center of our Milkey Way namely Sagittarius A* which is a believed to be a supermassive black hole with a mass greater that 4 million times the mass of our sun.
Global description of a possible journey:
Rough route map:
- Solar system:
Journey trough solar system starting from earth passing various planets.
- Oort cloud:
Crossing region between our solar system and deep space at a distance between 2000 and 50000 AU1 from sun. Recent studies show it to be a remnant of the protoplanetary disc that was formed approximately 4.6 billion years ago
- Rho Ophiuchi:
One of the closest star formation regions in the galaxy towards our solar system
- M22 (Messier 22): globular cluster at distance of about 10600 light years from eart
- M28 (Messier 28): globular cluster at distance of about 17900 light years from earth
- M9 (Messier 9): globular cluster at distance of 25900 light years from earth close to the center of our Milky Way
- Arrival at OGLBE-2005-BLG-390Lb
Brief overview of current tracks of the OGLBE-2005-BLG-390Lb series:
Thematic track on starting of the voyage from earth
Thematic track on planet Mars
Thematic track on planet Jupiter
Thematic track on signals received from various pulsar1 located in deep space2. This track features various pulsars including PSR B1933+16 (app 900 000 years old), PSR B1822-09 (app 200000 years old, located in the constellation Scutum at distance of app 1 kpc from the sun) and PSRB 0531+21 (Crab Nebula Pulsar, created in 1054 AD as remnant of the supernova SN1054, located in the center of the Crab Nebula)
Thematic track on planet Saturn.
Thematic track on planet Uranus
Thematic track on spaceship being hit by high speed/energetic meteoroids near the Kuiper belt. This belt is situated in the outer regions of our solar system. It consists mainly of small bodies and remnants from when our solar system was formed.
