This online-only monthly journal is a multidisciplinary journal for the field, representing — and fostering closer interaction between — all of the key astronomy-relevant disciplines, by publishing the most significant research, review and comment at the cutting edge of astronomy, astrophysics and planetary science
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study like types of planets around other stars.
NASA’s New Horizons spacecraft is healthy and speeding across the Kuiper Belt. On Oct. 2, we’ll be crossing a distance marker of note, passing 60 times as far from the Sun as Earth is. Put in perspective, that means we’re almost twice as far out as Pluto was when we explored it!
A new study authored by NASA’s New Horizons team reports the detection of an unexpected population of very distant bodies in the Kuiper Belt, an outer region of our solar system populated by ancient remnants of planetary building blocks. The newly detected objects stretch out to almost 90 times as far from the Sun as Earth.
Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA’s New Horizons spacecraft, by making the most precise, direct measurements ever of the total amount of light the universe generates.
The Subaru Telescope's wide and deep imaging observations are contributing information to the New Horizons spacecraft as it moves through the outer Solar System. By applying a unique analysis method to images of Kuiper Belt objects taken by the Subaru Telescope's ultra-wide-field camera, objects that have the potential to extend the Kuiper Belt region have been discovered.
Mission scientists are pursuing new research goals and making unique astrophysical and heliospheric observations with the suite of instruments onboard New Horizons, taking advantage of the spacecraft’s unique position in the distant Kuiper Belt.
The spacecraft continues to collect round-the-clock data on our Sun’s cocoon in the galaxy, called the heliosphere, and transmit that data, as well as the final data from our flyby of Kuiper Belt object (KBO) Arrokoth, back to Earth.
New observations from NASA’s New Horizons spacecraft hint that the Kuiper Belt – the vast, distant outer zone of our solar system populated by hundreds of thousands of icy, rocky planetary building blocks – might stretch much farther out than we thought.
Principal Investigator Alan Stern writes that NASA’s recent announcement that it’s extending New Horizons through 2028-2029 is good news, because it allows the mission team to make plans with NASA for a range of science and to expand its searches for a new flyby target.
