Dates of sun’s entry into each Zodiac constellation

Dates of sun’s entry into each zodiacal constellation and the corresponding ecliptic longitude (sun’s position in degrees, east of the March equinox point).

EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68 at a time when the universe was less than 600 million years old. The illustration shows the remarkable progress made in recent years in probing early cosmic history. Such studies are important in understanding how the Universe evolved from an early dark period to one when galaxies began to shine. Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation.

Astronomers measure most distant galaxy

The galaxy, called EGSY8p7, is about 13.2 billion light-years away. That means astronomers are now seeing it as it existed just 600 million years after the Big Bang.

How sunlight pushes asteroids

What makes the difference between a near-miss asteroid and a potential hit? Scientists think it might be related to a force called the Yarkovsky effect.
