There has been a high energy survey for the previous Universe; there was an infrared observatory to find out the formation of stars, galaxies as well the planet. Along with a Venus, the orbiter is to be also considered for ESA’s fifth medium-class mission in its Cosmic Vision science program which is scheduled to be launched in the year of 2032.

The three candidates are supposed to be The Transient High Energy Sky, and Early Universe Surveyor, The Space Infrared Telescope for Cosmology and Astrophysics and the Envision mission to Venus were selected from the 25 proposals that were received by the scientific community. As per the latest release, Theseus, Spica, and EnVision will the center of attraction for analysis purpose, and the result is expected to come out by 2021.

Theseus is considered to be an original mission which is supposed to monitor transient events belonging to the high energy universe among the whole sky and covering the entire cosmic history. To be precise, it will make a complete census of the gamma rays emissions from the first billion years of the universe. This will eventually help to shed light on the life cycle of the original stars.

It is believed that gamma rays bursts do get released during a supernova, or at the time when a dying star collapses after such an explosion to form a neutron star or even a black hole for instance. Theseus is supposed to provide proper locations of such high energy events that take place. Such position can also be tracked with the help of other space or ground-based facilities operating at corresponding wavelengths. In addition to the activity as mentioned above, Theseus will be able to follow up on the gravitational wave observations by finding out and identifying radiation from sources which is spotted by other detectors.

Understanding the concepts of the galaxies, stars, planets, and lie is itself a critical topic within the subject of astronomy. These topics can be very well realized with the help of sensitive infrared survey, which goes through the clouds of dust that typical hides the sites of the star birth.

Spica, which is a joint venture between the European and the Japanese project offers significant improvements in far infrared spectroscopic as well as survey capabilities over the NASA’s Spitzer as well as ESA’s Herschel Space Observatory to ensure continuing advances can be made in this sector.
