"For a brief time this month, Taurus will appear to have two eyes as Mars (upper left) moves northwest of Aldebaran (below center), as in this 2023 photo. Comet C/2022 E3 (ZTF) is also visible here, to Aldebaran's lower left." Astronomy Magazine, July 2024, p. 28. - Alan Dyer
Planetary Reports generated by "TheSkyX" software. These reports provide predicted data for the planets for the first of each month for the current year. The rise and set times for the Sun and the Moon for each day of the month as well as meteor shower radiants are also included in the reports. These reports have been optimized for the Denver, Colorado location, however, the times will be approximate for other locations on Earth.
(Times are Mountain Daylight Time (MDT) unless otherwise noted. Times will vary slightly depending on your location.)
"The planets are spreading out this month. Mercury and Venus lie in the evening sky; after midnight the next set of planets rises one after the other, led by Saturn. It's followed into the early-morning sky by Neptune, Mars, Uranus, and Jupiter. Saturn in particular is stunning, with the rings at their narrowest for the year." Astronomy Magazine, July 2024, p. 28.

"Combining images from orbit with images from the surface, a JPL-developed tool allows researchers to zoom in to see individual boulders and zoom out to see all of Mars.
Mars rovers can only make exciting new discoveries thanks to human scientists making careful decisions about their next stop. The Mars 2020 mission is aimed at exploring the geology of Jezero Crater and seeking signs of ancient microbial life on Mars using the Perseverance rover. Scientists at NASA's Jet Propulsion Laboratory in Southern California used novel mapping techniques to direct both the rover and the flights of the Ingenuity helicopter, which rode to Mars on Perseverance — and they did it all with open-source tools."
Read the latest news and discoveries from JPL's dozens of active space missions exploring Earth, the solar system and worlds beyond.
"Made famous in 1995 by NASA's Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty.
Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA's Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds.
"By flying past and amongst the pillars, viewers experience their three-dimensional structure and see how they look different in the Hubble visible-light view versus the Webb infrared-light view," explained principal visualization scientist Frank Summers of the Space Telescope Science Institute (STScI) in Baltimore, who led the movie development team for NASA's Universe of Learning. "The contrast helps them understand why we have more than one space telescope to observe different aspects of the same object." "
"Infrared imagery from the solar-powered spacecraft heats up the discussion on the inner workings of Jupiter's hottest moon.
New findings from NASA's Juno probe provide a fuller picture of how widespread the lava lakes are on Jupiter's moon Io and include first-time insights into the volcanic processes at work there. These results come courtesy of Juno's Jovian Infrared Auroral Mapper (JIRAM) instrument, contributed by the Italian Space Agency, which "sees" in infrared light. Researchers published a paper on Juno's most recent volcanic discoveries on June 20 in the journal Nature Communications Earth and Environment."
"Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make it a candidate well-suited for further study using NASA's James Webb Space Telescope.
TESS stares at a large swath of the sky for about a month at a time, tracking the brightness changes of tens of thousands of stars at intervals ranging from 20 seconds to 30 minutes. Capturing transits — brief, regular dimmings of stars caused by the passage of orbiting worlds — is one of the mission's primary goals."

JMARS is an acronym that stands for Java Mission-planning and Analysis for Remote Sensing. It is a geospatial information system (GIS) developed by ASU's Mars Space Flight Facility to provide mission planning and data-analysis tools to NASA's orbiters, instrument team members, students of all ages, and the general public.
"When a solar flare leaps out from around the sun, a small fleet of scientific instruments designed and built at the University of Colorado Boulder form a first line of defense—spotting these massive eruptions before any other instrument in space, then relaying the information to Earth in seconds.
On June 25, the fourth and final instrument in this suite, known as the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) program, is scheduled to launch into space. It will fly aboard the Geostationary Operational Environmental Satellite-U (GOES-U)—the latest in a series of GOES-R satellites that monitor weather on Earth from orbit. GOES-U, which will be renamed GOES-19 once it reaches geostationary orbit, will blast off from NASA's Kennedy Space Center in Florida on a SpaceX Falcon Heavy rocket.

The event marks the culmination of nearly 20 years of work for scientists and engineers at CU Boulder's Laboratory for Atmospheric and Space Physics (LASP)."
"The Sun will be at peak activity this year, providing a rare opportunity to study how solar storms and radiation could affect future astronauts on the Red Planet.
In the months ahead, two of NASA's Mars spacecraft will have an unprecedented opportunity to study how solar flares — giant explosions on the Sun's surface — could affect robots and future astronauts on the Red Planet.
That's because the Sun is entering a period of peak activity called solar maximum, something that occurs roughly every 11 years. During solar maximum, the Sun is especially prone to throwing fiery tantrums in a variety of forms — including solar flares and coronal mass ejections — that launch radiation deep into space. When a series of these solar events erupts, it's called a solar storm."
"After six months of effort, an instrument that helps the Mars rover look for potential signs of ancient microbial life has come back online.
The SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) instrument aboard NASA's Perseverance Mars rover has analyzed a rock target with its spectrometer and camera for the first time since encountering an issue this past January. The instrument plays a key role in the mission's search for signs of ancient microbial life on Mars. Engineers at NASA's Jet Propulsion Laboratory in Southern California confirmed on June 17 that the instrument succeeded in collecting data.
“Six months of running diagnostics, testing, imagery and data analysis, troubleshooting, and retesting couldn't come with a better conclusion,” said SHERLOC principal investigator Kevin Hand of JPL."
"In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet.
Mars scientists have been anticipating epic solar storms ever since the Sun entered a period of peak activity earlier this year called solar maximum. Over the past month, NASA's Mars rovers and orbiters have provided researchers with front-row seats to a series of solar flares and coronal mass ejections that have reached Mars — in some cases, even causing Martian auroras.
This science bonanza has offered an unprecedented opportunity to study how such events unfold in deep space, as well as how much radiation exposure the first astronauts on Mars could encounter.
The biggest event occurred on May 20 with a solar flare later estimated to be an X12 — X-class solar flares are the strongest of several types — based on data from the Solar Orbiter spacecraft, a joint mission between ESA (European Space Agency) and NASA. The flare sent out X-rays and gamma rays toward the Red Planet, while a subsequent coronal mass ejection launched charged particles. Moving at the speed of light, the X-rays and gamma rays from the flare arrived first, while the charged particles trailed slightly behind, reaching Mars in just tens of minutes."
"There's good news from NASA's Cloudspotting on Mars project! That's the project that invites you to help identify exotic clouds high in the Martian atmosphere.
Thanks to your help, the Cloudspotting on Mars project reached a huge milestone. Another full Mars year, Mars Year 30 (Oct 2009 — Sep 2011), has been completed! That's the second full Mars year of observations that has been analyzed since the project began.
A new project from the Cloudspotting on Mars team has started its beta testing phase! In this new project, you'll pick out cloud shapes in data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) Mission. If you're willing to help beta test this project and provide feedback before it launches, please send an email to the team. We'll let everyone know when this project officially launches, of course!
Congratulations to the Cloudspotting on Mars team and all the volunteers who have helped spot Martian clouds!"
"The 23-year-old orbiter is taking images that offer horizon-wide views of the Red Planet similar to what astronauts aboard the International Space Station see over Earth.
NASA's longest-lived Mars robot is about to mark a new milestone on June 30: 100,000 trips around the Red Planet since launching 23 years ago. During that time, the 2001 Mars Odyssey orbiter has been mapping minerals and ice across the Martian surface, identifying landing sites for future missions, and relaying data to Earth from NASA's rovers and landers.
Scientists recently used the orbiter's camera to take a stunning new image of Olympus Mons, the tallest volcano in the solar system. The image is part of a continuing effort by the Odyssey team to provide high-altitude views of the planet's horizon. (The first of these views was published in late 2023.) Similar to the perspective of Earth astronauts get aboard the International Space Station, the view enables scientists to learn more about clouds and airborne dust at Mars."
