Latest studies lend credence to the theory that the Milky Way has a large black hole at its center
Breaking the ice
Discovery of ice on the Moon might make colonising it and using it as a low-cost outer- space missions launching centre a less difficult target
Cousins in space
Observation of the star Lalande 21185 could lead to the first direct imaging of another solar planet
Witness to genesis
Cosmologists spy on galaxies being born, and conclude that these massive stellar assemblages might have formed earlier than believed
Far but near
Detection of two galaxies that are unassociated with a quasar raise further questions about galactic evolution
Hey, how old are you?
The age of a newly discovered galaxy defies the predictions of the standard cosmological model, meaning some more work for the theoreticians
Mystery behind the dazzle
Far away from the sun but exceptionally bright, the comet Hale-Bopp has baffled a lot of scientists who are struggling to explain its strange …
A Keck for the specks
The faintest and the most distant objects in the heavens no longer remain invincible with the introduction of the powerful Keck Telescope, the …
Another of the same kind
Geneva Observatory astronomers Study spectral lines in the visible spectrum and detect a planet thefirst to be observed outside our own planetary …
Stars apart
X-ray emissions from a contracting mass of gas far away in the universe raises questions about the birth of the solar system
Over before we knew it
Lenoid meteor shower, the biggest astronomical non-event of 1998, caused hardly any damage to orbiting satellites
Mars' water connection
Channels and valleys observed on the Martian surface and meteorites of Martian origin indicate that once there might have been water on the planet
