Sidewinding young stellar jets spied by Gemini South

Young stellar jets are a common by-product of star formation and are thought to be caused by the interplay between the magnetic fields of rotating young stars and the disks of gas surrounding them. These interactions eject ...

Astronomers find star fuel surrounding galaxies

Most galaxies, including our own, grow by accumulating new material and turning them into stars—that much is known. What has been unknown is where that new material comes from and how it flows into galaxies to create stars.

The gamma-ray binary HESS J0632+057

Gamma rays are the most energetic known form of electromagnetic radiation, with each gamma-ray being at least one hundred thousand times more energetic than an optical light photon. Very high energy (VHE) gamma rays pack ...

Hubble views a tranquil galaxy with an explosive past

The lazily winding spiral arms of the spectacular galaxy NGC 976 fill the frame of this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies around 150 million light-years from the Milky Way in the constellation ...

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.
