NASA’s Dawn Spacecraft photos reveal details of Dwarf Planet Ceres over 200 years since it’s discovery

 

Written by Elizabeth Landau

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Year’s Day, 1801, the dawn of the 19th century, was a historic moment for astronomy, and for a space mission called Dawn more than 200 years later. That night, Giuseppe Piazzi pointed his telescope at the sky and observed a distant object that we now know as Ceres.

Today, NASA’s Dawn mission allows us to see Ceres in exquisite detail. From the images Dawn has taken over the past year, we know Ceres is a heavily cratered body with diverse features on its surface that include a tall, cone-shaped mountain and more than 130 reflective patches of material that is likely salt. But on that fateful evening in 1801, Piazzi wasn’t sure what he was seeing when he noticed a small, faint light through his telescope.

Giuseppe Piazzi used this instrument, called a Ramsden Circle, to discover Ceres on January 1, 1801. The telescope is on display at the Palermo Observatory in Sicily. (NASA/JPL-Caltech/Palermo Observatory)

NASA’s Mars Reconnaissance Orbiter confirms Liquid Flowing Water on Mars

 

Written by Guy Webster / DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.

Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time.

They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. (NASA/JPL-Caltech/Univ. of Arizona)

American Heart Association says the result of eating too much Salt can be measured in Blood Pressure

 

American Heart AssociationDallas, TX – People who gradually increase the amount of salt in their diet and people who habitually eat a higher salt diet both face an increased risk of developing high blood pressure, according to a study published in the Journal of the American Heart Association.

In a Japanese study of more than 4,000 people who had normal blood pressure, almost 23 percent developed high blood pressure over a three year period. Those who ate the most salt were the most likely to have high blood pressure by the end of the study. Participants who gradually increased their sodium intake also showed gradually higher blood pressure.

American Heart Association gives Tips to reduce your Sodium Intake

 

American Heart AssociationNashville, TN – Americans’ love for salt is having a dramatic impact on their health. The average American takes in more than 3,400 milligrams of sodium each day—almost 2,000 milligrams more than the limit recommended by the American Heart Association (1500 mg/day).

Sodium is an essential nutrient and a little salt can be part of a healthy diet, but the amounts we are eating are far too high and can increase the risk of high blood pressure, heart disease, stroke, and other health problems.

Nearly all of the 1,000 people surveyed by the American Heart Association (97 percent) either underestimated or could not estimate how much sodium they eat every day. Too much sodium in the diet can increase risk for high blood pressure, stroke, heart disease and other major health problems.
