Kepler K2 finds 28 more exoplanets

March 11, 2019
.
Dear Exoplanet Explorers,
.
We’re very excited to let you know that we just published a new list of 28 new planet candidates identified thanks to your collective efforts!
.
EEplot
 
.
These planets are a varied bunch, with sizes ranging from two thirds that of Earth to  those which are more than twice the size of Neptune. All are quite some distance from their stars, so  are most likely not habitable – but don’t despair, as they will help us understand planet formation. You can read more here: http://www.jonzink.com/blogEE.html
.
These new exoplanet candidates range in size from ~2/3 the radius of Earth to nearly twice the radius of Neptune. As seen in the figure above, most of these planets are similar in orbital period and planet radius to the bulk population of K2 confirmed and candidate planets. However, this list provides 9 potentially rocky planets with radii less than twice that of Earth which is where we think planets transition from being primarily rocky like Earth and have a thick gaseous atmosphere like Neptune. The radius cut off for rocky planets remains somewhat unclear as the composition of the planet is the important feature to consider here.
.
Unfortunately, transiting planets only provide us with the planets radius. Nevertheless, optimistic estimates suggest that planets smaller than twice the radius of Earth may be rocky. For further reading on this topic check out the associated paper! As the search continues for habitable planets, these rocky planets are of unique interest as they potentially mimic the environment we experience here on Earth. The planets in our list are outside the habitable zone, but there are some candidates that are close. We need better stellar properties, which might indeed show that some planets could be in the habitable zone.

If you’re missing the search for new planets while Exoplanet Explorers is taking a break, please help our friends over at Planet Hunters with their search through data from TESS, NASA’s newest planet-seeking mission. You can get involved at www.planethunters.org.
 
Thanks for all your help!

Ocean heatwaves devastate wildlife, worse to come

Invisible to people but deadly to marine life, ocean heatwaves have damaged ecosystems across the globe and are poised to become even more destructive, according to the first study to measure worldwide impacts with a single …

Due to humans, extinction risk for 1,700 animal species to increase by 2070

As humans continue to expand our use of land across the planet, we leave other species little ground to stand on. By 2070, increased human land-use is expected to put 1,700 species of amphibians, birds, and mammals at greater …

Red tide rolling: Harmful algae found to flourish in both high-, low-CO2 environments

The algae responsible for Florida’s toxic red tides may be more resilient to shifting ocean chemistry than scientists previously realized, according to research from Florida State University oceanographers.

Dying trees in cities? Blame it on the concrete

A North Carolina State University study examining urbanization, scale-insect abundance and latitudinal warming on tree health in the Southeast captured a few surprising results.

Sonar disturbs blue whales feeding

No one really knows why pods of whales spontaneously drive themselves aground. Military sonar may be one culprit, and the need to train and test submarine tracking technology in open water could put the US Navy in conflict

Green water supplies and global limits

Access to dwindling freshwater supplies is one of the defining issues of our time as global populations expand amidst a changing climate. Water access and limitations and related issues are rightly considered a possible flashpoint …

Chemical pollutants in the home degrade fertility in both men and dogs, study finds

New research by scientists at the University of Nottingham suggests that environmental contaminants found in the home and diet have the same adverse effects on male fertility in both humans and in domestic dogs.

Catastrophic outlook for African savannahs due to rise in CO2 levels

A ground-breaking research study looking at modern and ancient landscapes has discovered African plants could be facing mass extinction faster than once thought.

Swiss nerds to launch exoplanet measuring CHEOPS space telescope next year

November 14, 2018

Swiss nerds are awesome.  They were the ones to discover the first exoplanet in 1995.  In 2019, CHEOPS will be launched in order to measure the radii of exoplanets.  When radius and mass are known, the density of the planet can be calculated.  Here’s a boring video about the making of CHEOPS.  2019 will also reveal the early results of TESS to the public.

TESS now hunting for more Exoplanets

August 2, 2018

habit zone exoplanets

NASA’s Transiting Exoplanet Survey Satellite has started its search for planets around nearby stars, officially beginning science operations on July 25, 2018. TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth. The TESS Science Team will begin searching the data for new planets immediately after the first series arrives.

UPDATE: Kepler K2 3.5 years and counting

February 10, 2018

UPDATE 8.08.18:

Based on data from NASA’s K2 mission, an international team of scientists has confirmed 44 new exoplanets. This brings the total number of new exoplanets found with the K2 mission up to 347.

“We started out analyzing 275 candidates, of which 149 were validated as real exoplanets. In turn, 95 of these planets have proved to be new discoveries,” said U.S. doctoral student Andrew Mayo at the National Space Institute (DTU Space) at the Technical University of Denmark. “This research has been underway since the first K2 data release in 2014.”
