PERTH: A merger between the infant Milky Way and a smaller galaxy has been detected with the help of a new theoretical model, providing evidence that our galaxy is a barred-spiral galaxy.
The new model simulates a merger between a smaller galaxy and the Milky Way some nine billion years ago and shed light on how the Milky Way was formed, reveals its history of devouring smaller galaxies and may strongly support a new model of the galaxy formation.
As NASA prepares to wrap up its shuttle program, leaving open questions about what comes next for U.S. human spaceflight, the next big thing in NASA’s astronomy program has been dealt a blow. The James Webb Space Telescope, a tennis court–size spacecraft that would take up a position in deep space to peer farther than ever into the cosmos, has been in development as a replacement for and successor to the Hubble Space Telescope, which has already logged 21 years in orbit. But the House Appropriations Committee, in a bill announced July 6, proposed axing the project entirely this week, citing mismanagement and bad budgeting.

This finding adds to our knowledge of the fundamental properties of Neptune and also provides a mechanism for understanding how Neptune’s mass is distributed. The study could lead to a better understanding of the giant gas planets in general.
