A massive collision in the Milky Way's past

Our Milky Way galaxy has probably collided or otherwise interacted with other galaxies during its lifetime; such interactions are common cosmic occurrences. Astronomers can deduce the history of mass accretion onto the Milky ...

Galaxy blazes with new stars born from close encounter

The NASA/ESA Hubble Space Telescope has taken a new look at the spectacular irregular galaxy NGC 4485, which has been warped and wound by its larger galactic neighbour. The gravity of the second galaxy has disrupted the ordered ...

Stellar waltz with dramatic ending

Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object. It is most likely the product of the fusion of two stars that died a long time ago. After billions of years ...

Planet-hunter CubeSat images Los Angeles

A small satellite designed to hunt for new planets beyond the solar system recently looked down at Earth to capture an image of California's "City of Stars."

Brown dwarfs are formed in the same way as sun-like stars

Astronomers have discovered a so-called proto-disc around the proto-brown dwarf Mayrit. With this discovery, they were able to confirm for the first time that this celestial body was formed in the same way as sun-like stars.

Starship

A starship is a theoretical spacecraft designed for traveling between the stars, as opposed to a vehicle designed for orbital spaceflight or interplanetary travel.

The term is mostly found in science fiction, as humanity has not yet constructed such vehicles (while the Voyager and Pioneer probes have traveled into local interstellar space, they are not generally considered starships, mainly because they are both unpowered and unmanned). However, exploratory engineering has been undertaken on several preliminary designs and feasibility studies for starships that could be built with modern technology or technology thought likely to be available in the near future. For examples of such studies, see Project Daedalus, Project Orion, and Project Longshot.
