Recently in the Interstellar Category


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.

With the recent discoveries of interstellar objects `Oumuamua and Borisov traversing the solar system, understanding the dynamics of interstellar objects is more pressing than ever.

Voyager 1 - one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space - still works and zooms toward infinity.

The interstellar traveler, 2I/Borisov, is the first clearly active extrasolar comet, ever detected in our Solar system.

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.

The first known interstellar object to pass through our solar system is likely a piece of a Pluto-like planet from another solar system, according to a new study published as a pair of papers today in the Journal of Geophysical Research Planets.

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).

More than 40 years since they launched, the Voyager spacecraft are still making discoveries.

`Oumuamua and Borisov were the first two interstellar objects confirmed in the Solar system.

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.

It lacks the drama of a shape-shifting alien creature, but another threat looms over the prospect of generations-long, interstellar space travel: Explorers arriving on Xanadu could face problems communicating with previous and subsequent arrivals, their spoken language having changed in isolation along the way.

A mission to study the interaction of the solar wind with the ancient cast-off winds of other stars, and the fundamental process of particle acceleration in space, has completed a critical NASA review and is now moving closer toward a scheduled launch in 2024.

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

One year ago, on Nov. 5, 2018, NASA's Voyager 2 became only the second spacecraft in history to leave the heliosphere -- the protective bubble of particles and magnetic fields created by our Sun.

A U.S. rocket stands at its launch pad at the Wallops Flight Facility in Virginia counting down to a Thursday morning launch. On the other side of the world in Kazakhstan, a Russian rocket is being processed for its launch Friday afternoon.

'Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the Solar system.

Life On A Starship

A group of students and researchers at Delft University of Technology are designing a starship capable of keeping generations of crew alive as they cross the gulf between stars - and they've turned to ESA for the starship's life support.

In October astronomers were surprised by a visitor that came racing into our solar system from interstellar space.

Achieving relativistic flight to enable extrasolar exploration is one of the dreams of humanity and the long term goal of our NASA Starlight program.

According to Alphonse Swinehart via Vimeo "In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it's unfortunately very slow."

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.

Alpha Centauri As Seen From Saturn

The nearest star system (and the destination of Breakthrough Starshot) the trinary star Alpha Centauri, hangs above the horizon of Saturn.

Plans for Earth's first starships are being announced today in New York City. At a midday press conference, Yuri Milner's Breakthrough Prize Foundation is unveiling its latest project: "Breakthrough Starshot".

The team responsible for the Oscar-nominated visual effects at the center of Christopher Nolan's epic, Interstellar, have turned science fiction into science fact by providing new insights into the powerful effects of black holes.

The "tsunami wave" that NASA's Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen in interstellar space.

Visiting Interstellar's Spacecraft

I had an opportunity to stand next to a spaceship from the film "Interstellar" last Friday and fly through a simulation of yet another spacecraft from the film.
