We develop a model for an interstellar communication network that is composed of relay nodes that transmit diffraction-limited beams of photons.

The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size ∼100 m.

One of the most exciting findings in planetary science in recent years is the discovery of interstellar objects passing through our solar system.

Astronomers have been waiting decades for the launch of the James Webb Space Telescope, which promises to peer farther into space than ever before.

A search was conducted for laser signals, both sub-second pulses and continuous emission, from the regions of the sky opposite Proxima and Alpha Centauri.

When the four-decades-old Voyager 1 and Voyager 2 spacecraft entered interstellar space in 2012 and 2018, respectively, scientists celebrated.

Within just two years, two interstellar objects (ISOs) - Oumuamuas and Borisov - have been discovered. Large quantities of planetesimals form as a by-product of planet formation.

New observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pristine ever observed.

Motivated by recent visits from interstellar comets, along with continuing discoveries of minor bodies in orbit of the Sun, this paper studies the capture of objects on initially hyperbolic orbits by our solar system.

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL).

Two extrasolar objects, 1I/'Oumuamua, 2I/Borisov, have passed through our home system in just the last three years. Such interstellar objects provide a previously unforeseen chance to directly sample physical material from other stellar systems.

Low-mass probes propelled by directed energy from earth are an early option for exploration of nearby star systems. A challenging aspect of such technology is returning scientific observational data to earth.

Engineers for NASA's Voyager 2 spacecraft are working to return the mission to normal operating conditions after one of the spacecraft's autonomous fault protection routines was triggered.

The Pioneer 10 and 11 and Voyager 1 and 2 spacecraft, launched in the 1970s, are heading out of the solar system.

Astonishingly, not one but two interstellar asteroids have been detected entering our solar system since 2017.

Get Ready For More Interstellar Objects

Gregory Laughlin and Malena Rice weren't exactly surprised a few weeks ago when they learned that a second interstellar object had made its way into our solar system.

This paper discusses the physics, engineering and mission architecture relating to a gram-sized interstellar probe propelled by a laser beam.

In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of the speed of light to reach the Alpha Centauri star system within 20 years.

The Breakthrough Starshot initiative aims to launch a gram-scale spacecraft to a speed of v∼0.2c, capable of reaching the nearest star system, α Centauri, in about 20 years.

Last month The Breakthrough Foundation announced its plans for humanity's first interstellar mission, Project Starshot. While much has ben written about that announcement, only the basic details behind the technology have been released. Until now.
