The Event

As part of Global Goals Week, the Skoll Foundation and the United Nations Foundation are pleased to present We the Future: Accelerating Sustainable Development Solutions on September 21, 2017 at TED Theater in New York.
The Sustainable Development Goals, created in partnership with individuals around the world and adopted by world leaders at the United Nations, present a bold vision for the future: a world without poverty or hunger, in which all people have access to healthcare, education and economic opportunity, and where thriving ecosystems are protected. The 17 goals are integrated and interdependent, spanning economic, social, and environmental imperatives.
Incremental change will not manifest this new world by 2030. Such a shift requires deep, systemic change. As global leaders gather for the 72nd Session of the UN General Assembly in September, this is the moment to come together to share models that are transforming the way we approach the goals and equipping local and global leaders across sectors to accelerate achievement of the SDGs.




Together with innovators from around the globe, we will showcase and discuss bold models of systemic change that have been proven and applied on a local, regional, and global scale. A curated audience of social entrepreneurs, corporate pioneers, government innovators, artistic geniuses, and others will explore how we can learn from, strengthen, and scale the approaches that are working to create a world of sustainable peace and prosperity.

does pluto have water or oxygen

December 1, 2020 by 0

[9] On 9 June 1988 the existence of the atmosphere was convincingly proven[1] by occultation observations from eight sites (the best data were obtained by the Kuiper Airborne Observatory). The ions are "picked up" by the solar wind and carried in its flow past the dwarf planet to form an ion or plasma tail. In 1988, 2002 and 2006 it was approximately constant and equal to 100 K (with uncertainty about 10 K), despite a twofold increase in pressure. The next source was the New Horizons Mission: Beginning with the closest Pluto encounter in July 2015, scientists had a clear view of all above and they verified once more: There is big amount of water on Pluto! "Pluto is small enough that it's just about almost cooled off but still has a little heat, and it's about 2 percent the heat budget of the Earth, in terms of how much energy is coming out," Binzel explained. As the solar wind encounters the obstacle formed by the ions, it is slowed and diverted, possibly forming a shock wave upstream of Pluto. Such measurements will enable the SWAP team to determine the rate at which Pluto loses its atmosphere and, in turn, will yield insight into the evolution of the Pluto's atmosphere and surface. Pluto is not visible in the night sky to the unaided eye. "So we calculated Pluto's size with its interior heat flow, and found that underneath Sputnik Planitia, at those temperatures and pressures, you could have a zone of water-ice … And there's clear evidence Mars once had a giant ocean that covered nearly 20 percent of the planet. And then the question becomes, what was it that caused this alignment?". [14][20][21] It is notable that the observed concentration of methane is 2 orders of magnitude higher than expected from Raoult's law on the basis of its concentration in surface ice and the ratio of the sublimation pressures of methane and nitrogen. It contains layered haze, probably consisting of heavier compounds which form from these gases due to high-energy radiation. Turns out that when you do the math, the only thing that explains that kind of alignment would be a big heavy ocean of liquid water. [8] This (but also changes in viewing geometry) results in appreciable changes of the brightness and color of Pluto. For heavier-than-methane hydrocarbons, water, ammonia, carbon dioxide and hydrogen cyanide, this pressure remains negligibly low (about 10−5 Pa or still lower), which indicates absence of volatility at Pluto's conditions (at least in cold lower atmosphere). Infrared photometry by the 4-meter Nicholas U. Mayall Telescope revealed methane ice[52] on Pluto's surface, which must sublimate significantly at Plutonian temperatures. It will last till equinox near aphelion (about 2113). % However, the situation is complicated by its big axial tilt (122.5°[43]), which results in long polar days and nights on large parts of its surface. VOA spoke about it with Richard Binzel, MIT professor of earth, atmospheric and planetary sciences. [2][18], The most volatile compound of the atmosphere of Pluto is nitrogen, the second is carbon monoxide and the third is methane. [33], Pluto has no or almost no troposphere; observations by New Horizons suggest only a thin tropospheric boundary layer. [4], Pluto is the only trans-Neptunian object with a known atmosphere. 1.3 Most important, it doesn’t matter how much oxygen is in the water because we absorb oxygen into our blood through our lungs, not our digestive tract. [10], Molecules with high enough velocity, which escape into outer space, are ionized by solar ultraviolet radiation. [5][21], Seasonal and orbital changes of insolation result in migration of surface ices: they sublimate in some places and condensate in others. − 1 Further research revealed that the temperature is strongly different in different regions: from 40 to 55–60 K.[1], Around the year 2000, Pluto entered star-rich fields of the Milky Way, where it will reside until the 2020s. [4], The temperature of the upper layers of the atmosphere does not show noticeable temporal changes. Horizontal extent of the layers is no less than 1000 km. ; for grazing light the effect is much stronger). ≈ Spectral data provided values 0.94 Pa in 2008 and 1.23 Pa in 2012 for the distance from the center 1188 km (1±4 km from the surface). [30][38] Atmospheric pressure turned out to be about 2 times higher than in 1988. Some measurements, such as temperature, pH, and specific conductance are taken almost every time water is sampled and investigated, no matter where in the U.S. the water is being studied. The methane content, according to measurements by New Horizons, is 0.25%. Approximately at the same time, the equinox occurred and the southern hemisphere became tilted towards the Sun. This is mainly due to atmospheric refraction (not absorption or scattering). This is caused by strong height variations of temperature. [9], The first strong, though indirect evidence of the atmosphere appeared in 1976. The indicator of volatility is saturated vapor pressure (sublimation pressure). [1], Existence of the atmosphere of Pluto was proven via stellar occultation. The radius of Pluto must also be known, but it was poorly constrained before 2015. The temperature and pressure themselves were impossible to calculate at the time due to an absence of data on the chemical composition of the atmosphere and a large uncertainty in the radius and mass of Pluto. Due to reverse direction of axial rotation of Pluto, naming of its poles is somewhat ambiguous. [1] As of 2015, it is moving away from the Sun and its overall surface illumination is decreasing. ), liquid water would immediately evaporate or freeze. [Note 4] It should cause strong changes in its atmosphere, although details of these processes are not clear. No. So far there's evidence of water on the exoplanet Ceres, three of Jupiter's moons (Europa, Ganymede and Callisto), three of Saturn's moons (Titan, Enceladus, and Mimas), and one of Neptune's moons (Triton). That means a person who weighs 100 pounds on Earth would weigh only 7 pounds on Pluto. The stellar light which managed to reach Earth during the occultation (due to refraction in Pluto's atmosphere), demonstrated an increase of intensity with wavelength. During the previous aphelion (1865) significant quantity of volatile ices were present in both the northern and southern hemispheres. Pluto's last passage through its perihelion was on 5 September 1989. Pluto has barely any gravity and an extremely low temperature of -230 degrees celsius. Firstly it was also interpreted as weakening of light by haze,[28] but now it is thought to be mainly a result of strong inverse temperature gradient in lower atmosphere. Its thickness in the place of measurement was 4 km, and the temperature was 37±3 K. The layer is not continuous. It does not have water on its moons . [4][7][29], Another evidence of the haze was obtained in 2002 due to a new occultation. [37][8][36][38] This is probably caused by Pluto's north pole coming into sunlight in 1987, which intensified evaporation of nitrogen from the northern hemisphere,[29][39][Note 3] whereas its southern pole is still too warm for condensation of nitrogen. 0.013 This can be explained by aggregation of small (tens of nm) particles into larger (hundreds of nm) clusters. The atmosphere of Pluto is notable for its strong and not completely clear seasonal changes caused by peculiarities of the orbital and axial rotation of Pluto. Binzel suggests that Pluto's crust is probably extremely thin in this region, allowing what's left of the planet's interior heat to reach the surface. [2][3][26] The layers show the presence of atmospheric waves (presence of which is also suggested by observations of occultations),[27][2] and such waves can be created by wind blowing over Pluto's rough surface. [10], Above it lays a layer with fast increase of temperature with height, the stratosphere. Still the idea is exciting to Binzel who says, "We are in a new era where water seems to be more prevalent than we had previously thought.". [8][12][57] The same year observations by the 3.0-meter NASA Infrared Telescope Facility revealed the first conclusive evidence of gaseous methane. [2][10], The main component of the atmosphere of Pluto is nitrogen. On any other planet (or moon, asteroid, etc. [1][2] It contains layered haze, probably consisting of heavier compounds which form from these gases due to high-energy radiation. Dependence on latitude or morning/evening conditions is also absent: temperature is the same above every part of the surface. [37][62][63], On 14 July 2015 the New Horizons spacecraft made the first explorations of the atmosphere of Pluto from close distance, including radio occultation measurements and observations of weakening of solar radiation during flight through Pluto's shadow. [4][8][36], Curves of pressure vs. distance from the center, obtained from occultations in 1988 and 2002,[29] in combination with the now known radius of Pluto (1187±4 km[2]) give values of about 0.4 Pa for 1988 and 1.0 Pa for 2002. Another common measurement often taken is dissolved oxygen (DO), which is a measure of how much oxygen is dissolved in the water - DO … [14][19], Methane and carbon monoxide, due to their lower abundance and volatility, could be expected to demonstrate stronger deviations from pressure equilibrium with surface ices and bigger temporal and spatial variations of concentration. Pluto is too far away from the sun. [28][55][56], The question of composition was answered in 1992 via infrared spectra of Pluto by the 3.8-meter United Kingdom Infrared Telescope. − [5] An occultation on 4 May 2013 gave data almost precisely for the surface level (1190 km from the center, or 3±4 km from the surface): 1.13±0.007 Pa.[5] An occultation on 29/30 June 2015, just 2 weeks before New Horizons encounter, provided a surface pressure of 1.3±0.1 Pa.[37], The first direct and reliable data about the lowermost layers of the atmosphere of Pluto were obtained by New Horizons on 14 July 2015 due to radio-occultation measurements. [4][8] An occultation of an exceptionally bright star, about 10 times brighter than the Sun itself, was observed on 29/30 June 2015 – only 2 weeks before the New Horizons encounter. Best estimates are derived from measurements of thermal emission of Pluto. The overall change of atmospheric pressure in this model is about 4 times; the minimum was reached near 1970–1980, and the maximum will be near 2030. So, does this mean that Pluto, the wanna-be planet, might have life on it?. Its largest moon, Charon, is close enough in size to Pluto that it has become common to refer to the two bodies as a double system.Pluto is designated by the symbol ♇. As mentioned above, calculated total amount of water on Pluto in ice form is about 30% of the planet, where the rest 70% is made of the core with … Around 2035–2050, the southern hemisphere will cool enough to permit intensive condensation of the gases, and they will migrate there from the northern hemisphere, where is polar day. [29], Interaction with the atmosphere significantly influences the temperature of the surface. It could be due to the existence of separate patches of relatively clean methane ice, or due to an increased methane content in the uppermost layer of usual mixed ice. The atmosphere of Pluto is the tenuous layer of gases surrounding Pluto. It quickly increases with temperature, and at 60 K (close to the maximum value[1]) approaches to 10 000 Pa, 3000 Pa and 10 Pa respectively. [10], The haze is the most probable reason for a kink in the curve of light intensity vs. time obtained by New Horizons during the flight through Pluto's shadow (see image on right) – below altitude 150 km the atmosphere attenuates light much stronger than above. The next occultation observed was on 12 June 2006,[7][60] with later ones occurring more frequently.

This presumes a loss of several centimeters of nitrogen ice and several dozen meters of methane ice during the lifetime of the Solar System. Its blue color points to a particle radius near 10 nm, but the ratio of brightnesses at different phase angles indicates a radius exceeding 100 nm. Even if it does contain extra oxygen, a bottle of oxygenated water would have less oxygen than the amount you get taking a single breath. [2][40][3], The stellar occultation 17 July 2019 have shown the Pluto`s atmospheric pressure have dropped about 30% from maximal values in 2015, reaching 0.967+0.053−0.034 Pa.[41] 6 June 2020 further pressure decline to 0.91±0.03 Pa was measured. "... hydrogen and oxygen are the two most abundant compounding elements in the universe, so perhaps we should not be so surprised. So we asked, what's the chance of that randomly happening? The full temperature range is only several degrees. Earth is the only planet in our Solar System that has stable bodies of liquid water on the surface. 1 [29] Amplitude of these heterogeneities is estimated to be 0.5–0.8 K on the scale of a few km. {\displaystyle 1-e^{-0.004}\approx 0.4\%} The surface pressure was estimated to be 1 Pa (1.1±0.1 at entry of the spacecraft behind Pluto and 1.0±0.1 at the exit). The northern hemisphere will not lose its volatile ices completely, and their evaporation will supply the atmosphere even at the aphelion. [4][5][7] Causes of this decrease are unclear; it could be related to the cooling effect of carbon monoxide,[12] or hydrogen cyanide, or other reasons. It's not a liquid, flowing ocean, but maybe slushy. The first stellar occultations after 1988 were on 20 July and 21 August 2002 by teams led by Bruno Sicardy of the Paris Observatory[29] and James L. Elliot of MIT. It consists mainly of nitrogen (N2), with minor amounts of methane (CH4) and carbon monoxide (CO), all of which are vaporized from their ices on Pluto's surface. But how did an ocean form on Pluto? It provided the first direct measurements of parameters of the lower atmosphere. ≈ % For the lowermost layer of the atmosphere the scale height is about 17[20]–19[6] km, and for heights 30–100 km — 50–70 km. On average, Pluto’s temperature is -387°F (-232°C), making it too cold to sustain life, but it does have a heart-shaped glacier bigger than Texas.
