    A new study of Pluto's surface returned by the New Horizons spacecraft in 2015 has confirmed the presence of ice volcanoes on the dwarf planet's surface.

  • Study of Pluto’s subsurface ocean drives potential return mission

    Laurel KornfeldMarch 12th, 2022

    A $3 billion return mission to Pluto with an orbiter is being proposed to further study the subsurface oceans of both Pluto and its large moon Charon.

  • Sublimating nitrogen ice could be cause of polygons in Pluto’s Sputnik Planitia

    Laurel KornfeldJanuary 12th, 2022

    The unusual polygonal features seen in Sputnik Planitia, the left side of Pluto's iconic heart feature known as Tombaugh Regio, could be caused by the sublimation of nitrogen ice, a team of scientists propose in a study published in the journal Nature.

  • Pluto’s atmosphere may be starting to condense

    Laurel KornfeldOctober 12th, 2021

    Beginning three years after New Horizons' historic flyby, Pluto's atmosphere appeared to be starting to condense and refreeze, according to scientists.

    Laurel KornfeldAugust 1st, 2021

    NASA's New Horizons team released new movies simulating the spacecraft's 2015 flight over Pluto and its large moon Charon to mark the sixth anniversary of the encounter on July 14, 2015.

  • Surface, geology of Pluto studied via opposition observations

    Laurel KornfeldJuly 4th, 2021

    Six years after the New Horizons spacecraft returned close-up images of Pluto, researchers are teasing out more information about its geology and surface.

  • New Horizons spacecraft is now 50 AU from the Sun

  • Probe finds deep space is not completely dark

    Laurel KornfeldDecember 1st, 2020

    Now more than four billion miles away from Earth, NASA’s New Horizons spacecraft, acting as a distant space observatory, has found that deep space is not entirely dark.

  • Arrokoth’s flattened shape could shed light on planetesimal formation process

    Laurel KornfeldNovember 15th, 2020

    The flattened shape of the two lobes that make up Arrokoth, the Kuiper Belt Object (KBO) visited by the New Horizons spacecraft in January 2019, may hold clues to the formation process of planetesimals and even planets.

  • New Horizons parallax experiment observes an alien sky

    Laurel KornfeldJune 14th, 2020

    NASA’s New Horizons spacecraft, now over 4.3 billion miles (6.9 billion km) from Earth, successfully imaged two nearby stars displaced from the locations in the sky where they are seen from Earth in its April stellar parallax experiment.

  • SOFIA data sheds new light on endurance of Pluto’s atmosphere

    Laurel KornfeldJune 1st, 2020

    Data captured by the Stratospheric Observatory for Infrared Astronomy (SOFIA), an airborne observatory that studied Pluto’s atmospheric hazes just two weeks before New Horizons‘ 2015 flyby, indicates the hazes in Pluto’s atmosphere are regularly replenished.

  • New Horizons conducts parallax experiment; team searches for KBOs

    Laurel KornfeldApril 24th, 2020

    More than five billion miles from Earth and over 14 years past launch, NASA’s New Horizons spacecraft is conducting an experiment measuring the distance to two nearby stars while mission scientists are using Earth-based telescopes to search for new Kuiper Belt Objects (KBOs) for the spacecraft to study.

  • New Horizons parallax project seeks public participation

    Laurel KornfeldFebruary 21st, 2020

    NASA’s New Horizons mission is seeking public participation in a project aimed at imaging the two closest stars, Proxima Centauri and Wolf 359, from Earth on April 22 and 23, the same day the spacecraft will photograph them from almost five billion miles (eight billion km) away.

  • Pluto’s heart feature controls its winds

    Laurel KornfeldFebruary 20th, 2020

    Pluto’s iconic heart feature, named Tombaugh Regio, functions as a “beating heart” that controls the small planet’s winds and might even play a role in shaping its surface features.

  • Pluto’s hazy atmosphere is similar to that of Titan

    Laurel KornfeldFebruary 2nd, 2020

    Pluto is often compared to Neptune's largest moon Triton, but its hazy atmosphere is actually more akin to that of Saturn's largest moon Titan, which is sometimes viewed as an analog of early Earth.
