May Astronomical Highlights: Jupiter, Its Moons and a Meteor Shower
By Kelly Kizer Whitt
On May 9, Jupiter reaches opposition, when from our earthly point of view, it will be opposite the sun in the sky. Stargazers consider opposition the best time to view a planet, because it rises at sunset and sets at sunrise, making it visible all night long.
Look for Jupiter rising in the southeast amid the constellation of Libra the Scales. Jupiter will be the brightest point of light in this part of the sky, shining at magnitude -2.5. It stands out in this region because the stars of Libra aren't particularly bright, but two of them do have rather remarkable names. Zubenelgenubi is the star closest to Jupiter on the right, and Zubeneschamali is above Jupiter. These names translate to the southern claw and the northern claw, because Libra was once part of neighboring constellation Scorpius or the Scorpion.
If you have a telescope or even just a decent pair of binoculars, you can catch some good views of Jupiter throughout the month. Look for faint stripes of dark and light that make up stormy belts and zones in the atmosphere. These are actually easier to see than the Great Red Spot, which in reality is a rather bland, peach-colored swirl.
All four of the largest moons, known as Galilean moons, can be seen orbiting Jupiter on any given night, their configuration constantly changing. On May 9, Io is closest to the planet early in the evening but then moves out to trade places with Ganymede. Europa is the third moon on that side of the planet while Callisto is on the other side.
The moons pass in front of Jupiter regularly, causing small eclipses that we can see from Earth. Large telescopes might show the satellites in front of the giant planet, but less powerful optical aid should still be able to pick up the dark shadows of the moons as they cross the bright disk. Try May 19 when Europa and its shadow move across Jupiter, or May 23 or 30 when Io and its shadow pass in front of the planet.
Every so often two of the moons' shadows will cross at the same time, in what is called a double shadow transit. One of these will occur on Aug. 23 when Io and Europa's shadows can be seen on the planet at the same time just after sunset and before Jupiter sets. The satellites themselves will both be in front of the planet at first, and then as Europa moves off onto the black background of sky, its shadow becomes the second dark spot on Jupiter. Approximately 30 minutes later, Io will join Europa off to one side of Jupiter while just the two shadows remain in front of the planet. Jupiter will sink below the horizon before the shadows disappear.
Our own moon does its monthly dance through the sky, passing from new to full and back again as it skims across the ecliptic, meeting planets and bright stars along the way. For those up before dawn, the moon will be near Mars on May 6 and Mercury on May 13. The young crescent moon reappears in the west at sunset on May 16, meeting up with brilliant Venus on May 17. On May 21, the moon and Regulus are less than a degree apart. The moon waxes larger as it passes Spica on May 25 and Jupiter on May 27 before becoming the full moon on May 29. Finally, on the last evening of the month, the moon rises late right beside Saturn.
One last perk in May's night sky is the Eta Aquarid meteor shower, which peaks from around May 4 to 7. The radiant (the point in the sky where the meteors appear to originate) will appear in the southeast before dawn, but the nearby moon may dampen the show.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
