NASA Just announced that scientists have discovered 7 Earth-sized planets orbiting a dwarf star (named Trappist-1) located 39 light-years from Earth, raising the question of whether any of these might support life. A huddle of seven worlds, all close in size to Earth, and perhaps warm enough for water and the life it can sustain, has been spotted around a small, faint star in the constellation of Aquarius.It is the first time that so many Earth-sized planets have been found in orbit around the same star, an unexpected haul that suggests the Milky Way may be teeming with worlds that, in size and firmness underfoot at least, resemble our own rocky home.The planets closely circle a dwarf star named Trappist-1, which at 39 light years away makes the system a prime candidate to search for signs of life. Only marginally larger than Jupiter, the star shines with a feeble light about 2,000 times fainter than our sun.While the planets have Earth-like dimensions, their sizes ranging from 25% smaller to 10% larger, they could not be more different in other features. Most striking is how compact the planet’s orbits are. Mercury, the innermost planet in the solar system, is six times farther from the sun than the outermost seventh planet is from Trappist-1.Any life that gained a foothold and the capacity to look up would have a remarkable view from a Trappist-1 world. From the fifth planet, considered the most habitable, the salmon-pink star would loom 10 times larger than the sun in our sky. The other planets would soar overhead as their orbits required, appearing up to twice the size of the moon as seen from Earth.
Ethiopian Space Science Society is opening a call for Abstract submission for the upcoming The 11th Ethiopian Space Science Society General Assembly.

Participants are welcome to submit an abstract in the following topics; Astronomy and Astrophysics; Space physics; Plasma Physics; Atmospheric Physics; Geodesy; Geophysics; Remote sensing; and Aeronautics related topics.
Ethiopian Space Science Society held stargazing event at Janmedia on Thursday February 10, 2017 for school kids and there families. During the event the school kids observed the Moon and the planet Venus through a telescopes.
"I have never seen the Moon up close this way before, and I am really happy that I got a chance to observe the moon ... " said Yohanes one of the student who participated at the event.
ESSS aims to continue such stargazing events for the public in the future.
The 11th Ethiopian Space Science Society General Assembly is a two days event taking place in April 8-9, 2017 (Megabit 30 – Miyazia 01/ 2009 E.C) at Addis Ababa Institute of Technology Addis Ababa, Ethiopia with the presence of ESSS board members, branch leaders, institutional members, space science clubs leaders and individual members.
The general assembly includes discussion on the society affairs, presentations from the society branch offices, scientific paper presentations, space teamed exhibition, stargazing, youth presentation by the youth, award winning ceremonies for members who made great contributions to the development of the society and the space science technologies in Ethiopia. The program also includes pre general assembly TV students question and answers programs to promote the society and the science among the students and the community at large.
Stay tune, more information will be available soon!
