E KIPA MAI!

While ʻImiloa is closed to the public to help prevent the spread of COVID-19, we are shifting our attention to providing free online resources for our island communities and beyond. Our online resources page will offer make at home crafts, science and astronomy video clips, and more!

Build a black hole and play the orbit challenge!

How do I play?

Roll your bead, marble or other small spherical object into the black hole "cone". Black holes are gravity to the extreme! If you were to touch the surface of the black hole - which is called the Event Horizon - you would not be able to escape its immense gravity. As dangerous as a black hole is, you can orbit around it as long as you don't touch the event horizon. How long can your marbles orbit around this black hole before they touch the event horizon?

All About Black Holes

Did you know that Supermassive Black Holes are found in the centers of galaxies and are thought to be essential to galactic formation? Learn more about Supermassive Black Holes, Intermediate Black Holes, Stellar Mass Black Holes and Miniature Black Holes with this easy to make craft! Take a look!

Peeps Under Pressure

Learn about pressure as a Peep gets sent up to space!

Gravity Well Part 1

Join ʻImiloa Astronomer Emily Peavy as she walks us through the physics of gravity.

Gravity Well Part 2

In Part 2 of the Gravity Well Series, we learn about escape velocity... aka what it takes to beat gravity!

Black Holes

ʻImiloa School Programs Coordinator Punawai Rice gives us a delicious lesson on how Black Holes are formed. If viewing as curriculum, we recommend viewing the ʻImiloa@Home videos Star Sizes and Star Mass vs Star Size before viewing Black Holes. These videos can be found in the Constellations section below. Enjoy!

August 2020 Skywatch

BY ‘IMILOA ASTRONOMY CENTER

August brings the third of the four Star Families to the eastern night sky. Manaiakalani, The Chiefly Fishing Line, comprises the Summer Triangle in the northeast and Maui’s Fish Hook, Scorpio, in the southeast. The Summer Triangle represents a coil of fishing line that leads to the southeast and is secured to the top of Maui’s Fishhook. Manaiakalani fishes for Pīmoe, Sagittarius, the celestial crevalle (ulua) that swims towards the barb of Mauiʻs Fishhook. Click the link below for the complete information:

June 2020 Skywatch

June signals the last month in our discussion of the Star Family, Kaiwikuamoʻo, the Backbone. Kaiwikuamoʻo is described in the book, North Star to Southern Cross, written by the late Bishop Museum astronomer, Will Kyselka, and is one of four star families that modern day voyagers use to organize the night sky. To identify the Star Family, Kaiwikuamoʻo, look to the northeast and locate Nāhiku, the Big Dipper, a constellation of seven stars that resemble a ladle. The leading two pointer stars in the scoop of the Big Dipper point toward the star Hōkūpaʻa, Polaris, the north star. Polaris is at the very end of the constellation the Little Dipper. Both celestial ladles from the Big Dipper and the Little Dipper occupy the northeast quadrant of Kaiwikuamoʻo and the scoops pour towards each other.

Following the curving southerly arc of the handle of the Big Dipper leads to the brilliant red giant Hōkūleʻa, Arcturus, the fourth brightest star in the night sky. With a celestial latitude +19˚ north, Hōkūleʻa is the zenith star for the Hawaiian Islands. Continuing along the southerly track and crossing the celestial equator, we will arrive at Hikianalia, Spica, the southern pair star for Arcturus. Spica crosses just south of the Marquesas Islands, believed by researchers to be the homeland for the original settlers of the Hawaiian Islands. Following Spica southeast we come to the trapezoid constellation Meʻe, Corvus the Crow; a line through the center of the trapezoid and towards the southern horizon terminates our journey of "North Star to Southern Cross" with the constellation, Hānaiakamalama, the Southern Cross.

The Southern Cross is a significant constellation for early oceanic explorers sailing south towards Tahiti. The Southern Cross points toward the direction Hema, south on our star compass. Compasses, sidereal or magnetic, all work on the same principle. By pinpointing one known location along the horizon (magnetic north on the magnetic compass, or Polaris on the sidereal compass), you can identify the 32 headings of the magnetic compass and the 32 houses of the oceanic sidereal compass. At Kahikinui, along Maui's southern coastline, winds from the ʻAlenuihāhā Channel buffet the rugged shoreline. Along this windswept coast and in the shadow of Haleakalā is the archeo-astronomical site known asthe pānānā at Hanamauloa. The pānānā is a pre-contact navigational device or "sighting wall"; its possible function may have been to identify the celestial meridian and the point we call Hema, south on our sidereal star compass.

The wall is approximately 29' long, 5' wide, 5' tall with a 2′ notch at the center of the wall. Seaward of the wall at 213' distance sits an ahu, stone cairn. When siting through the notch and in the direction of the cairn, it provides the observer with a relative line of direction southwards along the celestial meridian. When Hānaiakamalama, the Southern Cross, is upright, it stands directly above the notch and frames the direction south. The pānānā at Hanamauloa serves as a navigational monument to voyagers from generations past.

Special Events

June 20th marks the northern hemisphere's Summer Solstice, the day when the earth's north pole is at its maximum tilt towards the sun. On this day the northern hemisphere experiences its longest period of daylight; the day length for Honolulu on the solstice will be 13 hours and 25 minutes.

Evening Observations

In the southern sky, careful eye observers will be able to see some notable stars and celestial objects. Just next to Hānaiakamalama we can see the two pointer stars Kamailehope, Alpha Centauri, and Kamailemua, Beta Centauri. These two stars will appear to be about the same brightness but they are quite different from each other. Beta Centauri is a triple star system of three bright stars that are about 400 light years away from us, meaning that it takes 400 years for light to travel from that star to Earth. Alpha Centauri, also a triple star system of smaller and fainter stars, is the closest star system to our Sun at only 4 light years away. So when you look at these two stars in the evening sky, the light from Alpha Centauri which enters your eyes left the star last U.S. presidential term, four years ago, and the light from Beta Centauri left the star before the United States was even a country, 400 years ago.

Not far from these notable stars, very careful observers will also be able to see the fuzzy light of a unique astronomical object, Omega Centauri. To find Omega Centauri locate Hānaiakamalama, the Southern Cross. From the crux of the cross draw a 45 degree line up to the north east of the cross; as you follow this line you will see a fuzzy smudge about 12 degrees north of Kamailemua, this will be Omega Centauri. Omega Centauri is a globular cluster containing about 10 million stars as it orbits around the plane of the Milky Way Galaxy.

Morning Observations

Early bird stargazers will enjoy a very different perspective of the night sky. As summer approaches, the sun will be rising earlier and the nights will be getting shorter. Throughout June, the sun will rise just before 6 am and the light of dawn will color our sky starting just before 5:30 am. In the early morning hours, the bright planet, Jupiter, and the fainter planet, Saturn, will be high in the south western sky. These two gas giant planets will continue to accompany each other through our early morning sky with the red planet Mars about 73 degrees to the east of them. By the second week of June, the incredibly bright planet, Venus, will rise just before the sun in the east.

Nā ʻOhana Hōkū ʻEhā, The Four Star Families, offers a way for you to get a complete picture of the night sky by being able to identify stars and constellations within a family and between families. We invite you to try out this tool by stepping out into your yard tonight to explore and become familiar with our tropical night sky.  Enjoy!
